ADJUSTABLE FLYBACK CONVERTER OR INTERMEDIATE BUCK CONVERTER Russian patent published in 2017 - IPC H02M3/335 H02M1/08 G05F1/565 H05B37/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used to control a flyback converter or an intermediate buck converter. Device and method for reducing distortions and increasing distortions power coefficients in flyback converters (21) and intermediate buck converters (22) includes assembly (1) for adjustment of control signals generated by controllers (2) to control switches (3) of the converters. Assemblies (1) increase or decrease time durations of the conducting state of switches (3) in response to increased or decreased amplitudes of voltage signals from sources (4) of voltage for powering the converters. In the preferred version the said durations, in fact, are proportional to sums of the voltage signals amplitudes and rated parameters. These rated parameters can represent amplitudes of other voltage signals, such as output voltages. Assemblies (1) are provided for controllers (2), which can provide only fixed durations, as well as for controllers (2), which can provide adapted durations by adaptable external elements.

EFFECT: technical result is elimination of undesirable losses in the network and in power generators and lower cost of single-cascade converters.
