Abstract

PURPOSE: To enable operating at any optional frequency together with to raise an economical property by connecting an alternative current electrical machine constituted of its each phase with symmetrical two windings to a circuit provided a diode bridge and a chopper between its direct current terminals.
CONSTITUTION: An alternative current motor M is commonly connected of its intermediate terminals 0 having symmetrical two windings at each phase, while one pair of diode bridge circuit of one side alternative current terminal being opened is constituted with diodes D11∼D14 and D21∼D24, together with choppers S1, S2 are connected between those direct current terminals, alternative current terminals of opened bridge circuits are connected to an alternative motor M on a reverse polarity respectively. In this manner when a chopper S1 is "on", a magnetic flux of each winding is on a positive direction, when a chopper S2 is "on", becomes to a negative direction, a revolving flux corresponding with an opening and closing period of choppers is generated, a circuit is simplified and an ecomomical property can be improved.
