ABSTRACT:
By driving the gate of a voltage-controlled semiconductor switch, positioned as the upper device in each leg of a DC to AC converter, from an extremely high impedance, the need for floating gate drive power sources is eliminated. The invention takes advantage of the inherent gate capacitance of the switch as an energy storage device.
