FIELD: electricity.
SUBSTANCE: inverter is controlled in self-oscillation regime with frequency determined with resonance circuit; at that, control pulses are shaped with possibility of switching the inverter at zero current value in resonance circuit, and increase of output voltage is provided owing to decreasing no-current condition and decreasing the duration of control pulses.
EFFECT: improving specific power of charging device owing to optimising the inverter operation.
