Hi there, im now doing my final year project. One of my task is using igbt to cut off the voltage. The problem i facing is whenever there's voltage or non at the igbt gate, the Vce still cut off to half of the input. It suppose to be Vce same with the input voltage when there's non voltage at gate, and drop when theres voltage at gate. Can anyone who expert in igbt help me pls. I already burnt 7 igbt so far which cost me lots of money. Im using irg4bc40w. Thanks in advance.
