Hey guys.
Im using 3 half bridge with ir2103 as gate driver to drive a bldc motor(foc).
As you can see in the picture i sent, after a low level on HIN input of ir2103 the gate of the mosfet has a 1 us delay to get low and mosfet turns off.And this will cause 2 mosfets in one bridge turn on.
Whats the problem?
Yello is high side gate signal.blue is low side gate signal.prple is hin input from mcu.
Here is schematics of gate driver.
