REVERSIBLE FREQUENCY CONVERTER

摘要

FIELD: electricity.SUBSTANCE: invention pertains to the sphere of electric engineering and conversion equipment, in particular to reversible static converters of electric energy designed as per the circuit of indirect electrical converters. To the circuit of the electrical converter auxiliary rectifying circuits are added; the latter contain a diode and a thyristor (a monitoring key) turned on in antiparallel way and coupled in series with circuits of the active rectifier arm.EFFECT: expanding functionality of the reversible converter; besides, the suggested device has sufficient universality and may be used for designing of electrical frequency converters within wide range of power used both for low- and high-frequency applications, at that the electrical converter may or may not contain braking circuit.2 cl, 3 dwg
