ABSTRACT:
A solar energy electric generating system for space vehicles is provided which directly generates alternating current from ambient light without the use of inefficient power conversion. Light incident to photocell arrays is mechanically or electrically gated to produce fluctuating DC. A number of transforming devices are provided to convert the fluctuating direct current to alternating current. By varying the frequency and duty cycle of the pulsing output voltage, frequency and phase relative to some reference may be controlled. Additionally, direct current may also be produced efficiently from the same photocell arrays. A closed-loop system is provided for regulation. The rotational torque produced by a rotating shutter version may also be used, under inertial navigation control, to provide a rotational torque for vehicle positioning.
