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.

Abstract: Methods and systems for controlling voltage switching are provided. One system includes a transformer having primary and second windings, and a plurality of switching devices, wherein at least two of the switching devices are configured to produce different voltage outputs from a voltage input generated at the transformer. The plurality of switches are electrically referenced to one or more voltages. The system also includes a drive arrangement connected to the plurality of switches and configured to receive one or more voltage control pulses through the primary windings of the transformer, wherein the drive arrangement switches one or more of the plurality of switches based on the one or more voltage control pulses.
