AC CONVERTER TO SUPPLY INDUCTOR Russian patent published in 1994 - IPC

FIELD: electrical engineering; power sources. SUBSTANCE: device has half-bridge resonance inverter with control unit and input capacitive filter built around transistors with back-to-back diodes and capacitors; placed across ac diagonally opposite pair of junctions of inverter are inductor, current sensor and voltage sensor. Control unit has two null detectors, two flip-flops, two switching circuits, two output stages and delay element. Enhanced reliability is provided owing to reduction of switching losses in transistors and diodes of inverter as switching is performed at zero current and voltage. EFFECT: enhanced reliability. 1 dwg
