Thanks~

However, I don't understand what you mean on

"but I suggest you try using the high for 120 degrees, open for 60
degrees, low for 120 degrees, open for 60 degrees waveform instead."

I am using hardware implement only, how to control the on / off time
for the FET?



The idea is like this:
