Hi guys, we are trying to use ir2113 to drive the IGBT for our project. We plan to make an H-bridge using the IGBTs but we cant drive the IGBT using our IC. When we tried placing our PWM as input in the HIN pin of the IC, the HO pin only outputs a straight DC voltage.
When we tried on the LOW side, it worked fine.
Our PWM is 0 to 5V
VCC = 15V
we followed the schematic in the datasheet of ir2113
can anyone suggest a specific configuration that we need to do to activate the HIGH SIDE.
some of our questions.
1. We are expecting to see a squarewave output in the HO pin for a PWM input in the HIN pin, is that correct?
2. If the IR2113 is a driver, how exactly is it able to drive the IGBT, is it because it increases the current? /voltage?
Thanks!
