A REGULATED RESONANT VOLTAGE CONVERTER AND A METHOD OF REGULATED RESONANCEDC-DC VOLTAGE CONVERSION

摘要

The present invention relates to electrical engineering, in particular to a regulated transistor resonant high-frequency voltage converter with excellent efficiency, high power and low in cost, which can be used in different fields, with direct and alternating high-frequency voltage output.The regulated resonant voltage converter comprises two circuits for the simultaneous flowing of direct and indirect currents of the half-bridge transistors.A method of the resonance conversion is carried out at the expense of use of the second resonant choke that consumes power from the resonant capacitor and transmits a part of power to the rectifying load.Due to the above during all modes of operation the transistors provide for commutation at zero currents and the current amplitude does not exceed the nominal value at the expense of power interchange that particularly excludes the dynamic overloads and losses.
