QUASI-RESONANT VOLTAGE CONVERTER WITH HIGH EFFICIENCY Russian patent published in 2024 - IPC H02M3/335 

FIELD: electricity.

SUBSTANCE: invention relates to conversion equipment. Disclosed is a converter, which comprises a single-cycle converter, connected by outputs to inputs of a transformer connected to a resonant oscillatory circuit consisting of a resonant inductance coil and a resonant capacitor, synchronous rectifier built on MIS transistor, installed between resonant inductance and resonant capacitor connection point on one side and control unit first input on the other side, a current sensor connected to the output of the transformer and to the second input of the control unit, wherein branches of the transformer are connected to the third and fourth inputs of the control unit, and the first output of the control unit is connected to a MIS transistor, and an output filter. An additional MIS transistor is installed, which is connected between the output of the transformer and the output filter, wherein the input of the additional MIS transistor is connected to the second output of the control unit.

EFFECT: reduced losses in rectifier circuit of converter and increased efficiency.
