Hi,
Thanks for the reply.
Sorry for the schematic error. Actually I used that symbol during design only to get the required pads on PCB, but otherwise I have made connections correctly and according to the datasheet. I had seen the output of IGBTs on DSO, by applying 12V to HVDC and I could...
Hello,
I have gathered few more inputs.
Please find them in the attachment.
I used PNP that is only for getting proper footprint. They are soldered correctly in the circuit.
The circuit is powered directly from 230VAC and is rectified to DC. The Bus voltage is around 340V DC.
I observed that...
Hello all,
Good day!
I am new to this forum thus please pardon me if I make any mistake while asking my question.
I have been trying to make a small VFD (variable frequency drive).
I have used STGP19NC60KD IGBTs for the purpose and using IRS2109S for driving the gate.
I am driving the IGBT with...
