VOLTAGE CONVERTER WITH INDUCTIVELY COUPLED RECUPERATION CIRCUITS Russian patent published in 2010 - IPC H02M3/335 

FIELD: electricity.

SUBSTANCE: voltage converter includes transistor switch the control and power inputs of which are the first and the second inputs of converter, and power output is connected to the third converter input through primary winding of the first transformer parallel to which there connected is the circuit from the first capacitor connected between output of transistor switch and cathode of the first diode and anode of the second diode the cathode of which is connected to the third input of converter; secondary winding of the first transformer is connected directly to the first converter output and through rectifier diode to the second converter output; at that, to converter there introduced are additional diodes and the second capacitor connected between anode of rectifier diode and cathode of the third diodes and anode of the fourth diodes, which are connected; at that, cathodes of rectifier diodes and the fourth diodes are connected to the second output of converter, and anodes of the first and the third diodes are connected to the second input and the first output of converter through primary and secondary windings of the second transformer respectively.

EFFECT: increasing efficiency of voltage converter owing to reducing the dynamic power losses.
