VOLTAGE CONTROLLED SEMICONDUCTOR SWITCH AND VOLTAGE CONVERTER CIRCUIT USING SAME

摘要

A voltage controlled semiconductor power switch including a bipolar transistor efficiently driven by a field effect transistor coupled between collector and base electrodes for providing a non-saturated conduction of the transistor and rapid switching speeds. The switch is employed in voltage converter circuits which require minimum dead time in the application of drive pulses, and have an efficient circuit operation and reduced circuit complexity.
