PUSH-PULL INVERTER Russian patent published in 2003 - IPC

FIELD: electronic engineering; inverters for various industries, agriculture, medicine, and domestic purposes. SUBSTANCE: proposed dc-to-ac push-pull inverter noted for enhanced loading capacity in comprehensive range of resistances at high frequencies of about 1 000 kHz and having two controlled switches, isolating capacitor, and control system is provided in addition with reactors and diodes whose anodes are connected to input terminal. Each arm of inverter is formed by respective controlled switch, reactor, and diode which makes it possible to maintain power balance under no-load conditions, to eliminate throughput currents, and to ensure balanced operation of transformer. EFFECT: enlarged functional capabilities. 1 cl, 2 dwg
