@@HaseebElectronics dear sir I have purchased handheld self battery powerd dso can it be safe to measure ac voltage with out isolation transformer as you described in your safety measures for dso,s
it is variable frequency, based on the cooktop size, because its inductance changes each time with change in cooktop base size. as the cooktop base behaves as core for this coil. so, microcontroller detects the zero crossing of the pulse and adjusts its frequency moreover the frequency is also adjusted based on the cooking profile and the required cooking temperature for more details check video numbers 548 549 550 for gate drive signal of the IGBT
@@HaseebElectronics thanks. You are great teacher. I’m exploring the ‘auto-resonant’ transformers for the project, for example adjusting the frequency according the load, but I want the load to be the standard mains frequency / voltage capable
in some models it uses 1 IGBT, 2 IGBT and some models have 4 IGBTs if the gate is charged. it will give continuity sometimes the internal recovery diode gives continuity as well

What is the output frequency of the resonant induction coil?
it is variable frequency, based on the cooktop size,
because its inductance changes each time with change in cooktop base size. as the cooktop base behaves as core for this coil.
so, microcontroller detects the zero crossing of the pulse and adjusts its frequency
moreover the frequency is also adjusted based on the cooking profile and the required cooking temperature
for more details check video numbers
548
549
550 for gate drive signal of the IGBT
most likely it is around 20-40KHz

GREAT WORK
Is it Ok to have 200mv DC on gate?
Could you do vid on transistors and venders so can see not high performing
Sir, your instructions is very clear and concise. Can you please make a video on how to install universal backlight driver ca288 on tv
excellent
most welcome
Excellent video 🇵🇰🇩🇪

Sir that circuit diagram 2 igbt s are shown. Sir why igbt short continuosly .
in some models it uses 1 IGBT, 2 IGBT and some models have 4 IGBTs
if the gate is charged. it will give continuity
sometimes the internal recovery diode gives continuity as well
Hello sir.. I want to know how to know the voltage across the Control switches? Is it 5V DC ?
Beautiful
it is my pleasure
Hi
What is voltage feed to coil
And ampere
Sir what is the reason of slow heating problm.. Check points pls
