Abstract

898,281. Semiconductor circuits. MULLARD Ltd. March 27, 1961, No. 11088/61. Class 40(6). In a switching circuit comprising a controlled semiconductor rectifier rendered conductive by a signal applied to its gate electrode and turned off by discharging a capacitor in the reverse direction through the controlled rectifier under control of an auxiliary controlled rectifier, the capacitor is charged via a second auxiliary controlled rectifier. As shown, the silicon controlled rectifier SCR1 is rendered conductive by a signal applied to the gate electrode g 1 to initiate a pulse through the load RL. SCR3 is rendered conductive at the same time (or later) so that capacitor C is charged resonantly via inductor L1 to a voltage greater than the supply voltage E. SCR1 is turned off by firing SCR2 so that capacitor C discharges via inductor L2 driving the cathode of SCR1 positive. L1 = L2. Fig. 1 (not shown) relates to a known circuit in which SCR3 is replaced by a diode and L1 > L2.
