Hello,

I was founding a Three phase IGBT inverter module for 3 phase motor drive and found FSAM10SH60A IGBT module. In it's datasheet page no.5 says

Supply voltage = 450V (Applied to DC-Link)
Supply voltage (Surge) = 450V (Applied between P & N)
Collector Emitter voltage = 600V


These given voltage data is not matching with my voltage. I am not understanding that Is is write and wrong component for my need?
Second question is What is VCC (control supply) current of this module?

Please help
 

Expensive, but usefull chip.
Max AC voltage = Max DC voltage * sqrt(2)
At the top of the Electrical Characteristics Control Part page on the datasheet it says VCC is 26mA.
 
The output line to line voltage based on DC link (without third harmonic tricks) is:

Vline to line RMS = VDC/2/√2*√3

For a 600V DC link this comes out as being 367V. With the addition of third harmonic of the fundamental you can squeeze another 15 -> 20% of that which comes out as being about 440V best case.
 
Thanks your replies,

My DC link supply voltage according to 400v/3P is 563vdc. I am not understanding why are you calculating Vline to line RMS?

Oh,
I have understood it. It's ok. I was not considering voltage according to IGBT output.
