Excellent and well-executed project. When connecting PV modules in parallel I recommend using diodes. Greetings from Poland.

[@theinnovati0nlab782]

Thank you so much! 👍👍👍 This a model constructive feedback, and I greatly appreciate it. I fully agree with you. I thought of adding the blocking diodes, but I was hoping that the solar panels should have been designed with them. However, I realized during the testing that the panels I am using didn't have reverse blocking diodes....for some reason. Thanks again for the great feedback.!

I am really involved with all your projects. I have the 1800W with the fan but looks like something is right because the CC potentiometer is unable to control the current. I ordered another unit to test. I changed the potentiometer with different 5K, 10K 2K and 1K and nothing. I even jumped from R30 to positive from the potentiometer SW502 and nothing.

[@theinnovati0nlab782]

Thanks a lot for being a valued supporter of our channel. I greatly appreciate it.👍👍 I am happy to help you troubleshoot the CC issue. Let me ask, what are you using the converter for? I have used quite a lot of these converters, and I have never had this issue. However, I also realized that depending on the nature of the load you are driving, adjusting the CC would sometimes only lead to a voltage drop - especially if you are powering a resistive load. I found that the CC adjustment works best for battery charging or for driving loads like high power LEDs. To increase the current turn, the pot counter clockwise (....that is with converter input to your left and output to your right). At the end of the pot rotations, you will hear some audible clicks....but the pot adjustment spindle will keep turning. So pay attention to the audible clicks as you get to the end - in both directions. As a way to test/check, try using your converters to charge some batteries or to drive a high voltage LED. But make sure that you re-install the original CC pot value that was on the unit... should be about 5K trim pot.

The problem is that I am trying to control the Constant Current to be able to charge at 2A only. When I use the 502W dial does not seen to be working. I changed the potentiometer for a new one, also changed for a 10K ohms and nothing.

[@e2nomy]

Hello Sir, thx a lot for this great project. I am interested by AC-AC (boost) bulk converter to have a "cleaner" system than ones TRIAC based. Do you know a cheap chinese AE board doing that ? or in general maybe you can be interested by such topic.

[@theinnovati0nlab782]

Thanks for the wonderful feedback. Regarding your AC-AC question, the only affordable option that comes to mind that would not distort the sine waves would be to build a low frequency soft iron core auto tranformer. The major downside is that soft iron core transformers tend to be heavy and very bulky. However, if weight and size are not deal breakers for you, that would be one way to go. Another (more complex) way would be to design a power system that involves AC - DC - AC. Essentially, you could use a couple of those used server power supplies to convert your mains AC(120/240V) to a DC power level.....then use a sine wave inverter circuit to build the custom AC voltage level that you need. I hope this helps. The Innovati0n Lab 💥 www.theinnovati0nlab.com

[@ara7878]

Guys, you are great. You shoot the right videos. I have a question for you. I thought about this problem if in dc/dc to separate the power supply. If to make from a separate step-up converter power supply for the controller and key transistor -12v. And power supply to the throttle could be supplied any and even lower than 10v. Then will we be able to power this dc/dc from one lithium bank at 3.6v. It is clear that the current on the transistor with a decrease in voltage will increase greatly, but this is not a problem, because we can increase the number of transistors and align them by current. As a result, we can try, I think so, because alkaline batteries can be used and they are not afraid of deep discharges to complete zero. This makes a lot of sense, since by completely discharging the battery we have more power than, for example, using acid batteries. I would like to know your opinion. Thank you.

[@theinnovati0nlab782]

Thanks a lot for your inspiring words! We definitely appreciate it.👍👍❤️ However, the converter has a minimum input voltage of 10V, and you can not go lower than that. Also, I highly discourage low voltage inputs because they lead to lots and lots of power losses due to high currents that need to be pushed through the converter to compensate for the low input voltages. With these converters, the higher the input voltage, the better the efficiency. I hope this helps. Success wishes. The Innovati0n Lab💥 www.theinnovati0nlab.com

[@presechmax]

У меня была идея повышать напряжение для моего электро велосипеда не с 12v до 50v как это обычно делают, а с 2v-4v до 12v и потом с 12v до 50v 30a. 2v потому что мои ячейки LiFePO4 имеют такое минимальное напряжение. Подскажите какой преобразователь сделать для этого или может возможно сделать сразу от 2v до 50v с КПД 90%. На выходе нужны 50-55v 1500w долговременных. Так же я думал применить похожую схему для получения из параллельно подключенных солнечных элементов 3 последовательно и n параллельно. Идея заключалась в том чтобы максимально сохранить силу тока подняв до высокого уровня порядка 100v или 200v чтобы потом инвертором сделать AC 220v. Так я и нашёл ваш канал.

[@theinnovati0nlab782]

Thanks for the great encouragement. 👍👍👍 I love it when great minds think outside the box. Kudos on your project idea. However, the major problem I see is that 2V will be too low for what you want to accomplish, and I honestly haven't seen any converter that could handle that low of an input voltage level. Let's do some quick math using your specs: Input voltage: 2V Output voltage: 50V Output current: 30A Output power: 1500W Efficiency: 90% 💥💥💥 Calculations: Required input power = 1500/0.9 = 1666.67W Rrquired Input current at full load = 1666.67/2 = 833.3A Honestly, it will be extremely difficult, super expensive, and bulky to build something like this - using today's technology.

@@madnomad6528 проблема в лишней электронике. Bms+pcm. Итак электроники много. Хотя я нашёл пару схем с автотрансформатором на кольце, а вроде dc-dc. Просто от ячейки это было бы технологичнее. Так что пойду через 2 ступени: 1) от 2v до 12v и 2) от 12v до 50v. КПД не выше 80%. Одна ячейка или параллель ячеек даёт хороший ток. Я прикидывал. Так есть выигрыш. Главное электронику сделать надёжной. Этот китайский 1800w не подходит. Схему взять и собрать свой.

[@InfinionExperiments]

@@presechmax BMS is very simple, only needs voltage reference, resistors, transistors, and a wire to each cell terminal. If you can convince a designer (myself included) that there is demand for such a converter, it can be made. Look at this video's demonstration. With this custom inductor, 35A increases the winding heat to 70ºC even though resistance is very low. 35A at 2V is only 70W with 100% efficient output. This inductor style is challenging to cool, and without any voltage to multiply the power the low voltage applications are unsuitable. However, another option for very low voltages is a switched capacitor charge pump instead of an inductor type of boost converter. The power density is reported as near 100W / mm^3. To achieve 1500W, a charge pump stage should be connected to the batteries, and additional voltage doubler stages should be added until the 1500W current is reduced to until it is cheap enough and compact enough to switch to an inductor or flyback transformer stage. Stage 1 charge pump = 1.5V 1000A, stage 2 3V 500A, 4.5V stage 3 333A, 6V stage 4 250A. Then use a 6:60V transformer with a 250A primary. Boost converters using inductors are most efficient when output:input boost ratio is 1:1, and least efficient in higher gains above 7:1. I have made an LED boost converter from 18V to 81V with 90% efficiency and 9V to 81V with 83% efficiency. But this is ok because the power is less than 40W and the heat is manageable. Anything larger than 7:1 you should consider a transformer with primary and secondary. The magnetic losses are better than inductors at a certain point. There are more options to produce high voltage, but you could get rid of your 50V motor for a low-voltage model. It would be much simpler.

Your all videos are informative and very useful for establishing new innovative ideas. I have 6 solar pannel of 550W and VOC of each panel is 50 volt DC. If required, I will buy more panel. Using ur idea I want to operate my EATON e series DX model 10kva online ups directly through above solar plates. Input VDC required for operating online ups is 144-155 VDC with maximum of 40 ampere. My question is 1. Whether I will be able to operate my online ups without battery and AC supply, only using solar DC supply? 2. If answer of 1 is yes, what converter we required to convert constant 145 to 155 volt DC supply from source voltage range of 180-300 VDC and constant current of 40 ampere? 3. Can we use the above online ups to run 3Hp single phase max 15 ampere induction motor? Kindly help us ......

[@theinnovati0nlab782]

Wondeful!! It seems you are working on a very exciting project. Very cool!👍👍👍 First of all, I won't recommend powering a heavy duty - high surge application straight from your solar array without any power buffer in between (battery system or large super capacitor banks). This video was intended to be an experiment to peak into a realm of what could be possible with more research, test, and observations. 10kVa is quite a lot of power to push out without having a power buffer between the solar panels and your converter....or at least a very smart MPPT controller. It seems that you may need a very efficient MPPT charge controller that could handle up to 300V of input voltage range to provide your desired output voltage range. Again, to run a system like this without a battery system in between, you will need an extremely smart MPPT system, and you also need to over design your solar array - possibly by a factor of 2. This means you may need a solar array capable of producing up to 20KW of power at peak irradiance. The smart MPPT system will continuously monitor the available power on your array - per the solar irradiance - and optimize the delivered power to your load without over stressing your solar panels.

Non synchronous topoligies for such high powers make no sence, this is a 50 years old topology.

[@VictorC173]

There are very low losses, because this is a boost converter, there is lower current on the output, but for buck topology, only way is synchronous switching for achieving high efficiencies.

[@theinnovati0nlab782]

Thanks for the objective feedback.👍 I see your point. Usually, my recommendation is to use MPPT charge controllers for their IV adaptability and optimization via incremental conductance. However, a few things: 1. While most of us in the more developed countries can afford these expensive new technologies as they hit the market, a lot of people in 3rd world countries can not. To some people, the cost of a 20A MPPT charge controller could feed an entire family for a whole month......no jokes. So, I will experiment on a 50-year-old technology if it sheds light on an affordable solution. 2. Some old technologies have proven to be reliable and still work till today. Yes, we know that those technologies may not be the most efficient, or the most compact, or elegant.....but a lot of people will choose affordability any day. 💥💥 How old are these technologies? Do they still work? - Power Transformers - Power Inductors - Wire-wound resistors -Vehicle wheels - Vehicle tires, ......etc. My point is that we should never discard or discourage an idea simply because the technology behind its theory of operation is 50 years old. This is my counterargument.😊 I appreciate the wonderful engagement. Respectfully, The Innovati0n Lab 💥 www.theinnovati0nlab.com
