STABILISED QUASIRESONENT CONVERTER Russian patent published in 2014 - IPC H02M3/335 H02M7/53846 

FIELD: electricity.

SUBSTANCE: invention relates to converting equipment and it can be used for power supply systems of radar stations, radio-technical facilities, automatic and computer facilities. Stabilised quasiresonant converter contains two in-series charging MIS transistors, two series-connected recuperating diodes, two series-connected capacitors, series-connected resonant capacitor and choke, power transformer, two rectifiers, two voltage dividers, filter capacitor, load resistor, modulating MIS transistor, two single-ended PLM-controllers, two control transformers, time-setting RC-circuit, emitter follower, two differentiating RC-circuits. There is measuring winding of power transformer, the second modulating MIS transistor, two single-ended PLM-controllers, three time-setting RC-circuits, two differentiating RC-circuits, the second emitter follower, two summators, integrator, filter, clock-pulse generator, trigger, two logical AND components with respective relations.

EFFECT: improving operational performance of the converter, reducing its weight and dimensions, increasing efficiency factor, improving reliability and expanding its application scope due to exclusion of magnet flux direct component in power transformer.
