POLYPHASE AC VOLTAGE REGULATOR Russian patent published in 2002 - IPC

FIELD: production of guaranteed regulated rated output voltage in power supply sources at a drop of the input voltage below the rated one, as well as for electric drive by regulating the output voltage towards increase or decrease as compared with the input voltage. SUBSTANCE: the regulator has in each phase a series-connected accumulating location and a load, as well as a reservoir capacitor that is parallel- connected to an accumulating location which consists of series-connected input key formed by opposite-parallel connection of a gate with a full control (a transistor in the given case) with a reverse-biased diode of the output key made similarly to the input one on a fully-controlled gate with a reverse-biased diode and connected to the point of connection of the input and output keys of the accumulating reactor the accumulating reactors of all phases may be polygon- or star-connected, the load may also be polygon- or star-connected. EFFECT: improved quality of input current, since the condition of continuous currents at the input is ensured, the level of the current load of the keys and the quality of the output voltage remaining the same. 3 dwg
