ABSTRACT:
Disclosed herein is a magneto regulator circuit for regulating charging of the battery by the output of a magneto alternator. The regulator circuit includes a first circuit operative for connecting and disconnecting the battery in series with the alternator to allow or prevent charging of the battery. The first circuit includes a thyristor having a gate and operative when a trigger signal is applied to the gate for connecting the battery in series with the alternator to allow charging of the battery, a trigger switch which can be rendered conductive, subject to the battery voltage, for applying the trigger signal to the gate, and a shut-off switch for rendering the trigger switch conductive. The regulator circuit also includes a battery voltage sensing circuit coupled to the first circuit for selectively rendering the first circuit operative to disconnect the battery from being connected in series with the alternator to prevent charging of the battery, the voltage sensing means comprising a by-pass switch operative when the battery voltage exceeds an upper charging limit, for rendering the trigger switch means non-conductive to prevent application of the trigger signal to the gate of the thyristor. The regulator circuit also preferably includes a tachometer output circuit coupled to the magneto alternator and to the first circuit for providing a tachometer output having a voltage with a magnitude substantially the same as the magnitude of the battery voltage.
