Abstract

1,079,967. Semi-conductor circuits. ASSOCIATED ELECTRICAL INDUSTRIES. July 5, 1966 [July 7, 1965], No. 28803/65. Heading H3T. [Also in Division H2] An inverter including main thyristors T4, T5 is driven by a square wave oscillator comprising transistors T2, T3 and a saturable transformer. A thyristor T1 connected in the supply to the oscillator enables the inverter to be started or stopped at will. The inverter may be used in a standby power supply, Fig. 2 (not shown). Starting the inverter.-The capacitor C1 is always charged from the D.C. source. When contacts MS1 are closed the contactor coil S is energized and operates contacts S1, S2, S3, so that capacitor C1 is connected to the thyristor cathode by contacts S1 and the thyristor is fired from the positive line through resistor R4 and contacts S3. The initial boost to the oscillator provided by capacitor C1 causes it to start at increased frequency. Zener diode Z2 stabilizes the oscillator supply voltage after the initial discharging of capacitor C1. Stopping the inverter.-Since the current in thyristor T1 reverses briefly at the end of each half cycle, this thyristor turns off automatically when the contactor is released. The inductive energy in the inverter output transformer turns off the last conducting thyristor in the inverter.
