TWO-STROKE DC-DC CONVERTER WITH THROTTLE IN SUPPLY CIRCUIT Russian patent published in 2021 - IPC H02M3/335 

FIELD: power converting equipment.

SUBSTANCE: proposed device 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. Device is a two-stroke DC / DC-converter. It comprises: main throttle with power winding, bridge circuit composed by power controlled switches (power transistors), transformer with primary and secondary windings, secondary winding rectifier, output filter capacitor, parallel to which load is connected, first and second diodes, additional throttle and additional capacitor.

EFFECT: disclosed technical solutions enable to reduce switching losses in power transistors of bridge circuit during their locking, which improves reliability of their operation and operation of two-stroke DC / DC-converter in general, and also increases energy conversion efficiency of energy.
