Abstract

1406840 Automatic voltage control TOKYO KEIKI KK 13 Sept 1972 [22 Sept 1971] 42556/72 Heading G3R [Also in Division H2] In an inverter of the type in which a pair of emitter followers Q1, Q2 feed opposite ends of the primary winding of an output transformer T1, the emitter followers are driven by a push-pull driver 21 the magnitude of signal from which is controlled by an auxiliary transistor Q5 in dependence on the output voltage from the output transformer T1. As described, a trigger pulse generator 41 periodically switches a flip-flop 42 so as to drive transistors Q3, Q4 alternately into conduction. The resulting waveform Fig.2 (not shown) is made trapezoidal by capacitor 19 so as to prevent simultaneous conduction of the output transistors Q1, Q2. The output voltage in winding 3 of transformer Tl is rectified at 31 and compared at 33 with a Zener diode reference voltage 32 and the conductivity of transistor Q5 thereby controlled so as to maintain substantially constant voltage across load 4. In Fig. 4, the emitter followers Ql, Q2 form part of a bridge with two other transistors Q1', Q2' and are driven by three windings of the driver transformer T2. In Fig.3 (not shown) transistors Q1', Q2' are PNP, the four transistors being driven by four windings of the driver transformer T2. Sine-wave inverters. In Fig. 5 (not shown) series and shunt resonant circuits are included between the secondary winding of T2 and the bases of transistors Q1, Q2 so that the emitter followers provide a sine-wave output.
