ABSTRACT:
Circuitry for converting the nominally 600 hertz output of a gasoline engine driven magneto to 60 hertz. A pair of oppositely poled controllably enabled full wave rectifiers is connected to the magneto and the load. A zero crossing detector is coupled between the magneto and a counter. A rectifier control circuit is responsive to the counter output for controlling which of the full wave rectifiers is enabled.
