Abstract
A conventional on-off voltage regulator responsive to the output voltage of the rectifier of a vehicular battery charging system, operates three circuits each containing a pulse transformer and its driving transistor and other components for controlling the three SCRs that provide the negative side of the rectifier bridge, so that they will either pass entire halfwaves or block completely. The other three rectifier elements of the bridge are ordinary diodes. With this arrangement the SCRs may have the same rating as the other diodes of the bridge, and the thermal load is evenly distributed, while an alternator having a permanent magnet field can be used.
