PUSH-PULL TRANSISTOR INVERTER Russian patent published in 1995 - IPC

FIELD: secondary power supplies. SUBSTANCE: inverter has d.c. power source, push-pull output stage built around power transistors and output transformer, control unit. Switching transistor determine direction of magnetization of output transformer core and additional transistor functions to determine time required to transmit energy through output transformer to load. Transistor control pulses are shaped so that during reversal of core magnetization additional transistor is cut off, which ensures no-current switching of output transformer primary windings. Lengths of pulses controlling additional transistor during core magnetization and demagnetization are equal which ensures equal degree of core saturation. EFFECT: improved design. 2 cl, 2 dwg
