TWO-CYCLE RESONANCE DC-DC CONVERTER Russian patent published in 2020 - IPC H02M3/338 

FIELD: physics; electricity.

SUBSTANCE: invention relates to power conversion equipment and is intended for conversion and control of energy consumed from DC source, and transmitting the converted energy to its receiver using a transformer link between the source and the energy receiver circuits. Invention is resonance type voltage converter. It contains: electric circuit in the form of the first and the second branches, each of which is connected between supply buses and is formed by two power keys connected in series with controlled direct conductivity and uncontrolled inverse conductivity, for example, field transistors. Besides, the converter contains the first and the second throttle. One output of the first throttle winding is connected to the connection point of power switches of the first branch, and one output of the second throttle winding is connected to the connection point of power switches of the second branch. Converter comprises first primary winding magnetically connected to secondary winding connected via appropriate rectifier to output filter capacitor, in parallel to which DC load is connected, and a second primary winding magnetically connected to the secondary winding connected through a corresponding rectifier to the output filter capacitor, in parallel to which the DC load is connected, besides, the capacitor and four diodes.

EFFECT: technical result is higher energy efficiency of electric power conversion.
