PUSH-PULL VOLTAGE CONVERTER Russian patent published in 2010 - IPC H02M7/5383 

FIELD: electric engineering.

SUBSTANCE: push-pull voltage converter is complemented with two accumulating capacitors, the second pair of resistive voltage dividers and the second pair of electronic keys, which would make it possible to charge and discharge accumulating capacitors through primary windings of transformer, their simultaneous operation (one of from charging current, other from discharging current) generates summarised magnetic flow, at the same time switching of electronic keys takes place at the moment of full charge of one accumulating capacitor and full discharge of the other one, i.e. at zero value of voltage and current, which made it possible to reduce switching losses and to increase reliability, at the same time possibility to twice use one charge of accumulating capacitor energy (charge current, and then discharge current) in operation of transformer considerably increased energy indices of push-pull voltage converter, and makes it an energy-saving device.

EFFECT: reduced level of switching losses, increased reliability and improvement of energy indices.
