Filed: 1964-11-11
Abstract: 1,083,867. Transistor switching circuits. SVENSKA ACKUMULATOR JUNGNER A.B. Nov. 11, 1964 [Nov. 12, 1963], No. 45897/64. Heading H3T. [Also in Divisions G3 and H2] An inverter giving a sine wave output has two single pole change over switches (each formed in Fig. 2 by a pair of transistors 1, 2 and 3, 4) arranged as shown between the D.C. source 10 and primary 6 of the output transformer 5. The output waveform from the secondary 7 is filtered to give a sine wave, but the timing of the switching may be arranged so that no third harmonic is produced. Two oscillators 8, 9 whose frequency depends on their supply voltage each comprise two transistors in push-pull and a saturable cored transformer (Fig. 4, not shown). One oscillator is supplied from a reference voltage, which may be the main input, and the other is supplied by the rectified and filtered output of the inverter. Each oscillator drives one pair of transistors and the oscillators are synchronized by the connections shown in Fig. 9. In the more detailed circuit (Fig. 7) the main transistors 31 to 34 are shunted by reverse current diodes 48 to 51 since the circulating currents flowing during the periods when the inverter output voltage is zero would otherwise require the main transistors to carry reverse current. To reduce losses due to base current when the transistors are reverse biased, each of the transistors 31 to 34 obtains its drive current through auxiliary transistors 52 to 55 from windings on current transformers 40, 44 in series with the primary 36 of the output transformer 35. These windings are directed so that the associated transistors cannot receive drive current when they would be carrying main current in the reverse direction. The auxiliary transistors are driven directly from the oscillators. In another arrangement (Fig. 3, not shown) each pair of transistors is connected to a centretapped transformer to form a parallel inverter, and the two inverter outputs are connected in series.
