Abstract

1312420 Automatic voltage control MOTOROLA Inc 19 April 1971 [13 May 1970 26 May 1970] 27172/71 Heading G3R [Also in Division H1] A voltage regulator for a brushless alternator, has a stationary primary winding 114a of a transformer 114 fed by an oscillator 110 which is controlled by a voltage sensing circuit 112 connected to the stator output 126 of the alternator, the rotatable secondary winding 114b of the transformer supplying the rotor excitation voltage. A plurality of resistors 154 to 157 and a short circuit connection 160, are connected to a switch board 159 and provide the setting for the voltage regulator, thermistor 168 providing temperature compensation. In oscillation transistors 116, 117 alternately conduct until interrupted by the conduction of transistor 144 or 145, the lengths of the periods of such interruption being determined by the load requirements of the alternator, at maximum load producing a continuous output. In an alternative embodiment Fig. 2, (not shown), the feedback for the oscillator is provided by a saturable transformer (51).
