#About Half bridge driver

I am building synchronous boost converter circuit in which iam using half bridge driver for generating complementary PWM with dead time and iam trying to connect HO of half bridge driver to the gate of high side IGBT( IKZA75N65RH5) and LO of half bridge driver to the gate of low side IGBT( IKZA75N65RH5).But those are not connecting.could you please tell me what might be the reason.

Check out this example as a guideline of how to connect the gate driver to a DC-DC converter: https://www.mathworks.com/help/sps/ug/buck-converter_example-ee_switching_power_supply.html

My guess is that you are using PS control ports in IGBTs while the gate driver is giving electrical connections. If that's the case it won't connect, you will need to enable electrical connection in the IGBTs.
