Abstract
A gate drive circuit device includes positive and negative pulse circuit portions each including a pulse diode and a pulse assembly connected in parallel with each other. The pulse assemblies each include another pulse diode and a resistor-capacitor assembly connected in series. The resistor-capacitor assembly includes a pulse resistor and a pulse capacitor connected in parallel. Each pulse circuit portion is connected with a different switch. Each pulse circuit portion is a passive device that is configured to activate a different switch responsive to receiving one or more voltage pulses from a power supply.
