IGBT PWM controller finished.

Machine Specifications:
Input 120 to 240 volts AC, single or 3 phase, DC 120 to 400 Volts.
Circuit breaker 50 Amps
Maximum current 100 Amps
Pulse current 200 Amps
Output 0 to input voltage.(400 volts max on DC)
Just a quick demo and some explanation of my finished PWM controller, using MG100Q2YS1 IGBT module.

Greetings from Greece , I have a question , why you are not using any gate resistor Rg in your schematic ?

[subcooledheatpump]

@savvas2000 You're right, my mistake. There should be a 10 ohm resistor in series with the gate driver. Thanks for pointing that out

Hey there friend many thanx for commenting on my video on IGBT collection. You asked if thay all work and yes there all working.. and I'm wanting to build a zvs driver and using an IGBT module as the replacement transistor! Iv been looking on google images for a circuit that helps to wire them up correctly.as I'd be cutted if I destroyed one! So if you know of a circuit that would do for the IGBT to replace the transistor then that would be great. Many thanx friend. ;)

@high1voltage1rules What kind of ZVS circuit do you want to make? for a flyback driver, boost converter or induction heater? each one is a little different. I can help you if you give me a little more info

[subcooledheatpump]

Okay, the diagram is now posted, there is a link in the description.

I tried to make it as clear as I could. Don't forget, tie the green and black wires togther on the PC powersupply, else it won't start.

[maddkraut03]

can you publish a diagram somewhere/ would be helpful, great job. 

[subcooledheatpump]

@maddkraut03 Diagrams aren't one of my fine points, but I'll try my best to make one. There will be a link to it in the description when I'm done.

As iv git many the same that are fast switching. Couldn't fit that in. Lol

it doesn't really output pure DC until you add a diode,inductor and capacitor to make it a buck converter.

sensitive electronics such as audio amps and microcontroller doesn't like PWM as power input :(
