AC-TO-DC VOLTAGE INVERTER Russian patent published in 1997 - IPC

FIELD: electrical engineering. SUBSTANCE: inverter has current transformer, single-phase rectifier bridge with terminal leads for load connection; converter uses two controlled and two noncontrolled valves and control system coupled with current transformer and controlled valves; novelty is that current transformer has two primary windings connected in series with valves coupled with one of terminal leads so that load current flows through primary windings of current transformer in turn. EFFECT: improved reliability. 3 cl, 5 dwg
