POWER GENERATOR

摘要

A power generator comprising a pulley-driven alternator having three output windings in a delta configuration and a pair of rectifiers associated with each output winding; a voltage regulator for controlling the alternator output; and a capacitive voltage multiplier circuit; the voltage regulator being supplied with rectified current from the alternator windings via the rectifiers and controlling the current supplied to the field winding of the alternator; characterised in that the voltage multiplier circuit comprises a first pair of series-connected capacitors connected across the positive and negative poles of the rectified alternator output; a first blocking diode with its anode connected to the positive pole of the rectified alternator output and a second blocking diode with its cathode connected to the negative pole of the rectified alternator output; and a second pair of series-connected capacitors connected between the cathode and anode respectively of the first and second blocking diodes; the opposite ends of one alternator output winding being connected intermediate the respective capacitors of the first and second pairs of series-connected capacitors.
