Title: Voltage regulation for static inverter - uses diode in oscillating circuit preventing extinction voltage loss when supply interrupted
IPC: H02M1/06
Filed: 1976-09-17
Abstract: The regulator is for use with a static inverter which supplies power for a three phase asynchronous motor contains the principal thyristor and also an extinction thyristor in parallel with an LC series oscillating circuit. A diode prevents capacitor discharge when the power supply is interrupted. In a regulator circuit a load (30) is supplied through a principal thyristor (4). An extinction thyristor (5) is used to cause a current flow in the opposite direction to current flow in the principal thyristor. This is obtained from a series LC (7, 8) oscillating circuit in parallel with the extinction thyristor. The capacitor is charged to the extinction voltage after each extinction process and a diode (6) prevents the capacitor discharging when the supply is interrupted.
