RESONANT CONVERTER OF DC VOLTAGE INTO DC AND AC AND METHOD TO CONTROL ITS OUTPUT VOLTAGE Russian patent published in 2012 - IPC H02M3/338 

FIELD: electricity.

SUBSTANCE: in an available resonant converter with a serial circuit L, C, there is a parallel circuit from an inductance L2 of a transformer and a series capacitor C2, besides, Q-factors of circuits make 1.5. To the upper (or lower) valves of the inverter pulses arrive with a duration equal to a half-cycle of resonant quality of circuits, and to the lower (or upper) valves - pulses, duration of which complies with adjustment, besides, the period of inverter switching is by 4-5% more than the period of circuit oscillations, and either fronts of pulses or their centres match.

EFFECT: converter has smaller dimensions, higher efficiency factor, wide range of adjustment, low multiplication factor of currents, harmonic current of valves, independence of an output voltage on a load, a simple control device and simplicity of tuning.
