RESONANCE COMMUTATOR SWITCH (VERSIONS) Russian patent published in 2013 - IPC H02M1/06 

FIELD: electricity.

SUBSTANCE: device contains the first key (1) with back-to-back connected diode, the second key (2), capacitor (3) and inductor (4) connected in-series with the first key (1); output of the anode of back-to-back connected diode forms a negative power lead of the resonance commutator switch while output of the inductor (4) connected to one output of the second key forms a positive power lead of the resonance commutator; it is assumed that the capacitor (3) is connected in parallel to the second key (2) which second output is connected to the negative power lead of the resonance commutator switch.

EFFECT: reducing dynamic losses in power commutator switches of pulse-type regulators, inverters and active front ends.
