ABSTRACT:
A power supply monitor is disclosed for monitoring the finely regulated voltage in a two-stage tracking power supply which is driven by a gas turbine engine and which has a coarsely regulated and a finely regulated stage. A reference voltage is generated using power taken from the coarsely regulated stage and the reference voltage is compared with a voltage derived from an output of the finely regulated stage. If an unacceptable difference between the compared voltages is detected, controls are activated which prevent acceleration of the engine. The monitor is activated only after the engine reaches a selected speed and testing circuitry is provided.
