IGBT Drive
Hello Styx,
There is a simple way to obtain different speeds to turn on and off an IGBT. Use a diode with a low value resistor for the charging circuit of the gate, and in an antiparallel configuration, another diode with a higher resistor value for the discharge path.
In this way you can obtain a very high turn on speed, limiting the losses during the pass thru the unsaturated region, and a moderated turn off speed, decreasing the over shoot voltage to a reasonable level.
