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