Thanks, I had a concern of the size of the transformer, but your option of isolating DSO is good one.

[@vijayakumarkumar9190]

Very good and useful information sir thanks for sharing this knowledge to us

[@HaseebElectronics]

Most welcome

[@Telectronics]

Very nice but there is also a third way you can buy an active isolated oscilloscope probe for measuring anything high voltage or ground related. It gives you the opportunity to measure with both channels at different ground levels as well without shorting your probe because both are isolated from each other.

[@HaseebElectronics]

you are exactly right differential probes are very useful but these are expensive as well i am thankful for your valuable comment

[@Telectronics]

yes you are right they are not the very cheap. I also bought a cheaper chinese one from migsig dp10013 they are the cheapest ones I could find at the market and I am glad that they measure well enough at least for my hobby use. In some cases it´s better to get a differential probe than a heavy and also expensive isolation transformer variac combination. If it helps you are welcome my friend.

amazing work haseeb sir, please show us the zero crossing pulse and vce pulse of the igbt as well ,(that uses 820k to the microprocessor for timing and cookware detection)..we would be really happy to see that one.

[@HaseebElectronics]

sure i will explain it

[@alfredrein699]

Thanks, that help much. I afraid always, the IGBT regulate wrong if I give the Gate an other Signal over the resistor of the Oscilloscope. If I have 2 IGBT´s, one is off and the other is at this moment on. Maybe both IGBZs get out of sync and there is a moment where both are switched on at the same time. Then it crashes. Can I be sure that this does not happen during the measurement during operation?

[@limeadevs1131]

Which is better or more advantageous, to get a more expensive and larger isolating transformer and use it connected to the measured object, or to get a cheaper and smaller transformer and use it exclusively connected to the oscilloscope? Well thank you.

[@Dc_tech386]

Hello sir a quick question why pnp of high current rating can fully turn of a mosfet or igbt gate faster enough for zero heating but resistor can’t do the same

[@limeadevs1131]

Please advise if it is possible to consider a 230V/115V, 100W autotransformer that does not have a PE conductor as an isolating transformer/I want to connect an oscilloscope to it? Oscilloscope is HANTEK DSO5102P, AC 100-240V 30W max.

[@aboimad5178]

Second question please can I do anything to decrease it's input power to let it work on 500w (on my ubs) ? Any hack I can do ? Like changing Hz

[@HaseebElectronics]

it is doable just you need to change the surce code for microcontroller so that it shouldn't generate voltage error

[@Swenser]

What's wrong with connecting negative probe of scope to negative terminal of capacitor in circuit? No need for isolating transformer then right? Are you only suggesting an isolating transformer Incase the negative probe hits the positive side of circuit , right?

[@HaseebElectronics]

please check this video for your detailed answer kzbin.info/www/bejne/Y3ycZ4Ojm9VpgpI and i will wait for your kind feedback. if we are testing isolated circuit. no need to isolate the oscilloscope. for unisolated circuits, we need to isolate circuit OR oscilloscope OR disconnect safety ground

[@aboimad5178]

وعليكم السلام ورحمة الله وبركاته جزاك الله خيرا What is the output voltage from the wirs ? Can I use my small dso150 20v oscilloscope whit a voltage dividing resistors?

[@HaseebElectronics]

it is 16 volt signal

[@al1996.]

Thanks for sharing sir👏👏👏..sir i hope you can read thise,,can i ask about smd capacitor how to know its value when it is shorted or open?or any method to know its real value or replacement value of smd capacitor.thank you in advance sir🙂🙂🙂..

can we do the same test without the IGBT because I don't want it to be damaged i want to make sure that the gate signal is correct

[@HaseebElectronics]

sure i will explain it in detail

[@Questionmark47789]

Please explain through relevant diagram

[@dimitra.d792]

hi if the original igbt is without diode and replace it with one wich hase the same specifification but has diode is there problem in your opinion ?

[@electronicslover1120]

No problem just check current

[@mikrotech3103]

Haseeb bhai Yaha Pakistan mai kaun earth connect karta ha hamare yaha sirf phase aur neutral he aata ha ye unisolated se hame kya matlab..

you are right lekin is se DSO ya circuit damage honey k chances hotey hein

Sir 16.6v peak....and freqeancy i not get it😅....very noisy

that means there is something wrong which is creating noise you need to check it

Sir, without DSO how to chek igbt gate and emitter voltage. Same drive crkit (without igbt, when dame igbt that time remove igbt and chek) not chek digital multimeter?? Any make device for this signal voltage chek by multimeter??
