METHOD FOR REDUCING LOSSES IN A VOLTAGE INVERTER Russian patent published in 2008 - IPC H02M7/5383 

FIELD: electric engineering, possible use in electric energy transformers, wherein a parallel oscillation contour acts as energy consumer, for example, in transistor-based inductive heating generators.

SUBSTANCE: in accordance to the method, commutation of voltage inverter switches is performed at zero voltage by means of coupled a capacitor in parallel to each switch, selecting elements for matching serial oscillation contour and applying a special algorithm for controlling inverter switches: disabling of aforementioned switches identification performed in a certain time span after voltage integral for energy-consuming parallel oscillation contour passes zero, where aforementioned time span is determined on basis of condition of maintained value of phase shift between current integral for matching serial oscillation contour and voltage of energy-consuming parallel oscillation contour, inverter switches are enabled when zero voltage value is reached for them.

EFFECT: reduced losses in switches of voltage inverter which operates in inductive unbalancing mode for following components, connected serially: energy-consuming parallel oscillation contour and matching serial oscillation contour.
