Abstract
A half-wave regulator rectifier utilizes a silicon controlled rectifier (SCR) as the rectifying element between an alternator producing positive and negative voltage phases or waveforms and a battery charged by the alternator. The SCR is permitted to conduct charging currents through the battery during the positive voltage phases by means of a control circuit having a transistor connected to the control gate of the SCR. The control circuit monitors the alternator voltage and causes the transistor to inhibit conduction through the SCR above a regulated battery voltage unless charging current flows through the battery before the regulated battery voltage is reached by the alternator voltage. The regulator rectifier is protected against damage when abnormal conditions exist, such as no battery connection with the regulated system.
