STABILIZED QUASI-RESONANCE CONVERTER Russian patent published in 2012 - IPC H02M7/515 

FIELD: electrical engineering.

SUBSTANCE: introduction into control circuit of converter power circuit MIS transistors the summation unit and new links between elements that provide for modulation of output voltage with the frequency that is less than operation frequency of quasi-resonance converter and for using discrete voltage feedback in the circuit. Due to excluding from power circuit second secondary winding of power transformer, the power loss in windings decrease, thus the efficiency of power transformer increases. Also, exclusion of second secondary winding, second rectifier, modulating MIS transistor improve mass and dimension parameters of the converter.

EFFECT: expansion of the area of application of stabilized quasi-resonance converter with dynamic voltage instability on the output filter capacity with simultaneous increase of efficiency and improvement of mass and dimension parameters.
