ABSTRACT:
A direct current power controller for use in electrical control systems such as aircraft control circuits. The controller utilizes a field effect transistor (FET) as the switching element. A bias voltage supply circuit powers a gate driving circuit, current limiting circuit, and trip indicating circuit. Gate driving circuitry is not directly connected to the system ground, thus minimizing load interference with controller performance and eliminating the need for level shifting circuitry. Remote control circuitry is provided.
