Abstract

1,249,186. D.C. to A.C. converters. DANFOSS A.S. 6 Jan., 1969 [26 Jan., 1968], No. 728/69. Heading H2F. A three-phase bridge inverter (Fig. 1) having a common quenching rectifier E7, is controlled by an arrangement as shown in Fig. 2, wherein a 3-phase square waveform generator 8 produces outputs T, S, R at the required inverter output frequency, each half-wave of the outputs being used to send a train of h, f pulses to fire a respective one of the rectifiers E1-E6 by means of firing pulse circuits 13, 14, 15. In addition the square waveforms T, S, R, are summated, differentiated and rectified in a unit 12 (detailed Fig. 3, not shown) to produce from the leading and trailing edges of the resulting square waveform d at three times the inverter frequency a train e of quenching spikes at 6 times the inverter output frequency. The quenching pulses fire E7 (which is extinguished immediately afterwards by means not described) to turn OFF all conducting rectifiers. A main rectifier is fired again immediately after its quenching if its proper conduction period is not ended, a train of H.F. impulses being sent during the firing periods for rectifiers E1 to E6 as illustrated in Figs. 5f to 5l (not shown). Firing pulse units for main rectifiers.-A relaxation oscillator-R4, C1, L1 and unijunction transistor Tr3 (Fig. 4)-produces oscillations, e.g. 10-100 kc./s., which are passed by leads 16, 17 to firing pulse units 13, 14, 15. In unit 13, for example, as shown, when a positive half-wave from generator 8 output T is received at terminal 18, a current can flow only through diode D4, NPN transistor Tr5 and the primary of a transformer T3, and a train of high-frequency firing pulses are applied to rectifier E1 from output 1 during the whole of half-wave period. When a negative half-wave is received at 18 current flows through diode D3, PNP transistor Tr4 and the primary of transformer T2 producing firing pulses from output 2 to E2. Diodes D5, D6 ensure pulses of one polarity only at the outputs 1, 2. Control waveform generator.-The generator 8 (one unit of which is detailed, Figs. 6, 7, not shown) comprises a ring counter arrangement formed by a loop of three similar units 9, 10, 11 (Fig. 2) each of which integrates the square wave output of the preceding unit to form a constant amplitude trapezoidal signal from which is produced a constant amplitude square waveform output. The three outputs T, S, R are thereby relatively displaced by 120 degrees. By altering the amplitude of the square wave signals the frequency can be altered, e.g. proportional to the inverter output voltage, whereby a motor powered by the inverter maintains a constant magnetization independent of speed.
