VOLTAGE CONVERTER AND ITS CONTROL PROCESS Russian patent published in 2005 - IPC

FIELD: electrical engineering; static power converters.

SUBSTANCE: steady mode of sine-wave current resonant excitation is organized in voltage converter power circuit incorporating series LC circuit by means of proposed process, frequency of this sine-wave current being in step with operating clock frequency of converter. To this end automatic operating frequency and phase control unit is inserted in inverter circuit, its phase being synchronous with characteristic oscillations of series resonance-tuned LC circuit formed by isolating capacitor and dissipation inductance of power transformer.

EFFECT: reduced loss at switching members of inverter due to sine-wave type of handled current.
