FIELD: electrical engineering.
SUBSTANCE: method of autonomous matched resonant inverter control that contains valve switchboard arranged on controlled valves with inverse-parallel diodes and filter capacitor that works for loading parallel oscillating circuit, which is formed with load with inductivity and compensating capacitor connected to output terminals of valve switchboard through subsequent oscillating circuit formed by switching throttle and capacitor, consists in generation and alternate supply of control pulses to controlled valves of valve switchboard, which form direct and reverse half-waves of voltage at the load. Instantaneous values of voltages are measured in all controlled valves of valve switchboard and compensating capacitor. Moments of voltage instantaneous value transition through zero are defined at compensating capacitor. Control pulses are generated at the moments of voltage instantaneous value transition through zero at compensating capacitor. Alternate control pulses are sent to controlled valves of valve switchboard that form direct and reverse half-waves of current in load, at the moments of voltage instantaneous value transition through zero at compensating capacitor, if instantaneous values of voltage in all controlled valves of valve switchboard are simultaneously different from zero.
EFFECT: higher reliability of autonomous matched resonant inverter operation.
