ABSTRACT:
An electrical power supply system including an engine driven permanent magnet generator (11) operable to produce a variable voltage and high frequency output which is converted by a series train AC/AC conversion circuit (14) into a fixed voltage and relatively low frequency AC output for supply through a trip switch (56-58) to an external load (53-55). A bypass circuit including a pair of normally-closed parallel connected oppositely biased thyristors (66-68) is connected between the generator output and the output of the AC/AC conversion circuit (14).
