<P>PROBLEM TO BE SOLVED: To enhance an output by improving a force factor of a rotating machine all over the operating range including the number of revolutions. <P>SOLUTION: A snubber energy regenerative two-way current switch is connected in series between the rotating machine and a power supply or an electric motor and a load, and the switch is turned on or off by adjusting its phase to that of a flowing current. Thereby, a reactance voltage is compensated by accumulating magnetic energy in a capacitor and adding its voltage to the power supply voltage. As a result, the waveform of the flowing current is controlled and the force factor is improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
