Title: Controlled rectifier inverters
IPC: H02M1/08
Filed: 1973-08-22
Abstract: 1424055 Electronic counters V G YATSUK 22 Aug 1973 39709/73 Heading G4A [Also in Division H2] In a system for supplying trains of control pulses on output circuits 14 ... 19 for controlling an inverter, a plurality of thyristors 1 ... 6 are connected in series across a D.C. supply U1, each output circuit 14 ... 19 being coupled to a pulse forming means supplied by a respective one of thyristors 1 ... 6, the odd and even numbered thyristors being triggered by alternate pulses from a master oscillator 20. As shown in Fig. 4, the main inverter thyristors are triggered by wide pulses from transformers 34 ... 39 whilst the commutating thyristors are triggered by narrow pulses from transformers 14 ... 19. At the beginning of each cycle, transistors 27 and 33 are turned on, initiating wide control pulses from transformers 34, 39 produced by rectification of a train of high frequency pulses added to a supply U2. The first pulse from the master oscillator 20 turns on thyristor 1 which initiates a pulse in transformer 14. When capacitor 53 is sufficiently charged, avalanche diode 41 breaks down, turning on transistor 28 which initiates a wide pulse in transformer 35. Thyristor 1 also shunts the emitter/base circuit of transistor 33, turning off that transistor and terminating the wide pulse from transformer 39. The next half cycle from the master oscillator 20 triggers the thyristor 2 which initiates a narrow pulse in transformer 15 and after a further time delay due to capacitor 54, breaks down avalanche diode 42 and turns on transistor 29, initiating a wide pulse in transformer 36. The sequence continues until thyristor 6 is turned on, when a pulse, induced in winding ab of transformer 19, bottoms transistor 7 so as to turn off thyristor 1 and hence all the other thyristors. The wide pulses from transformer 34 ... 39 may last for 60, 120 or 180 degrees depending on the number of transistors bridged by the respective thyristors 1 ... 6. In Fig. 1 (not shown) only the narrow pulses are produced, each transformer 14 ... 19 being provided with a bias winding connected across the supply U1. In Fig. 2 (not shown) only the narrow pulses are provided, the primary of each transformer 14 ... 19 being connected in series with a respective capacitor between the positive side of the D.C. supply U1 and the junction of the respective thyristors 1 ... 6.
