Thanks for your effort I love your pattern of teaching very very understandable. Sir, my confusion is why did you select maximum duty cycle of 48% and from the datasheet of uc3843 it stated at 100% kindly explain more on it . Thanks

Amazing tutorial Good Info

[@jayabratabiswas01]

Sir, Thanks for posting this design series 🙏 I have a question regarding Bulk Capacitor calculations. You have considered Vpeak Minmum for Capacitor value. Why it is? Vpeak Minmum is the low voltage, why we are not considering the high voltage i. e. 375 volt. Other wise Bulk capacitor will not able to filter at high voltage. Please confirm 🙏

i have a question sir, the Vmin 85AC & Vmax265 is a constant value that will use everytime i design a circuit ? for example i need output 12Vdc/5A . the Vmin85V & Vmax265V is a constant value that i will use everytime i design a circuit?

[@lupojacobo9892]

[@NARESHKUMAR-ub2iq]

Sir I have a question. You use here 200KHz it's a typical value or maximum value of operating frequency?

[@rajeshn1322]

Please tell me calculation of EMI filter and current rating of all device

[@subirnath4229]

EMI filter kaya hota hai?....pls. explain & how to select right filter

[@bartdepauw1156]

Is the 2.5 factor depending on the Design ? So only for 'flyback' mode transformer ? What factor will be used for 'full bridge' mode ?

[@gajendraparmar507]

Hi sir, Based on which criteria you consider 200khz frequency ?

[@satishraju3582]

good . we need core selection and no of turns.

[@pradeepmaurya9321]

Thank you sir 🙏

[@mostafasaed4822]

Thank you dear But I found the inductance equation is different from the one you used.

[@HaseebElectronics]

you are right there are many approaches to calculate and each technique have its own equations.

[@mohammadmoezi3813]

hi sir...i saw your video and i want to say you are very good...excusme sir i want make one switching trans..with 220Vin and with +17v 0 -17v and .5amper but i dont know i must use how ferriet and typ wire...pleas lead me thankyou

[@sukhdeosingh617]

Sir kindly make video s on pwm sine wave inverter. Thank u.

[@friendman2001]

Where in the videos do you calculate the output capacitor?

[@bartdepauw1156]

Last step ( @11:54 ) surprised me : higher voltage needs a higher inductance ? ( changed from 414µH@100V to 502µH@110V ). So then it should be calculated at the Vdc high ?

[@HaseebElectronics]

No dear SMPS transformer is always calculated in Worst case scenario (Low input DC rail voltage and maximum power output) in this situation the IC will use maximum duty cycle. when DC rail voltage will reach at maximum level (i.e 375 VDC) at that time the ic will utilize minimum duty cycle to switch, to produce the same output power (which was being produced using maximum duty cycle at LOW dc rail voltage) *INDUCTANCE WILL BE CALCULATED AT Vin min*

[@MachiElectronicsLab]

Nice sir g sir please conform duty cycle how calculated or wh chose 0.48% in explain thanks

[@rain0aldwaib]

thank you for this tutorial but i want to ask if i want to design my own smps should i fallow all these videos 1 by one ?

[@BajisKitchen]

Honesty is the best policy allah bless you

[@chandanaranasinghe7197]

why use 0.48 as duty cycle? If we use 0.5 what happens? Should we allow Toff than Ton ?

[@MrKumar-il4xh]

One doubt i have, how did derive the Cin cap farmula and primary inductance.

[@denlo_12]

how is it come 0.48% duty cycle,kindly explain in detail plz Sir

[@rajeshbarlota7134]

If we keep the frequency high the power supply work properly or not because most of the power supply work in 50khz to 75kchz only. But u are using 200khz

[@friendman2001]

Where does 2.5 factor in inductor equation come from?

What is 2.5 and why 48% duty cycle

[@aleksandarjakimov6830]

@@HaseebElectronics but why exactly 48%? Is it necessary to be exactly that number and how that affect our circuit?

[@bartdepauw1156]

@@aleksandarjakimov6830 You still need to have a 'death' time ( both pulses are zero) per cycle. So 48 % is about the maximal time the puls can be high. With the 2 pulses per periode this makes 96% on and 4% off (= death time)

[@krishnamraaju6442]

Thanks you very much, small doubt in this video is,Lpri denominator constant term 2.5 but according to my calculations is 2 please confirm it

[@krishnamraaju6442]

NO, V=L*I/Ton E=1/2*L*i*i E=Pout/n*t

[@krishnamraaju6442]

so can you tell me,where i did the mistake please my request

[@chengwan1836]

E＝Pout/n*t, n=0.8 so it should be2.5
