FIELD: electricity.SUBSTANCE: suggested device is related to power conversion equipment; it provides energetic pulsed control method for power transmitted to load. Technical result is attained due to introduction of the first and second capacitors of input filter, the second controlled key element, the second valve element, the second capacitor of output filter, addition of the second winding of magnetic energy storage. The circuit consisting of in-series first and second capacitors of input filter is coupled between outputs of the output circuit of alternating line voltage rectifier. One output in the second winding of magnetic energy storage is coupled to the second output in output circuit of alternating line voltage rectifier while the second output in the second winding of magnetic energy storage is coupled to the device output bus through output circuit of the second controlled power key, besides this output is coupled to output bus of the device through the circuit, which contains the second valve element and in-series second capacitor of output filter.EFFECT: improved operational reliability of the device as well as reliability of pulse converters connected to output of the corrector of power factor and acting as the second power conversion stage thus ensuring galvanic isolation of the energy source and load.4 cl, 4 dwg |
