METHOD OF SINGLE-CYCLE VOLTAGE CONVERTER CONTROL AND DEVICE FOR METHOD IMPLEMENTATION (VERSIONS)

摘要

FIELD: electricity.SUBSTANCE: invention refers to electric converter devices and can be used in secondary electric power sources. Substance of method involves switch element opening at the moment of final demagnetising magnetic conductor in output converter during generation of relative span of open and closed state of electronic power switch element. Devices implementing the method include low-current control switch in converter control track, and discrete feedback signal of core demagnetising in output converter is fed to controlled input of the switch directly from primary winding (from demagnetising winding in the second variant) and prohibits power switch opening till the end of core demagnetising.EFFECT: reduced maximum current values and set power of power elements in converter, enhanced efficiency and reliability of converter.3 cl, 2 dwg
