PC817 example circuits

Abstract: opto isolator pc817 IGBT module being used. The 30V zener diode connected to pin 1 is necessary to protect the hybrid IC , zener diode. In order to size the resistor for minimum loss we must first determine the current , used. For example, if a 24V DC-to-DC converter is to be used then a 9V zener diode would give +15 , of the single supply and the zener diode can be varied to allow use of standard supplies. + , recovery diode (D1) is connected to the IGBT's collector to monitor the collector to emitter voltage
