Hi Engineers,
I am a mechanical engineer with barely some exposure to electronics.
I was trying to make a low power inverter using SG3525 as the gate driver as shown in the circuit below.

The gate drive waveform (At G1 and G2) is shown below.

The cycle time is 20 uS (Frequency = 50 KhZ) with dead time 2 uS.
My expectation was that the MOSFET would be turned OFF as soon as the gate goes LOW. Instead it kept on conducting partially for 2 uS before it turned OFF completely.
Contrary to my expectation that the MOSFET would be turned ON only when the gate goes HIGH, it started to conduct partially 0.50 uS before the gate went HIGH as indicated in the screen shot below.

Can someone explain why the MOSFET not switching properly and advice possible remedy?
Thanking you and with kind regards,
Job Thykkoottathil
