ABSTRACT:
A voltage detector detects the terminal voltage of a smoothing capacitor which is disposed between a converter for generating direct current and an inverter for generating alternating current. The presence and magnitude of regenerative power to the converter is judged by the detecting operation, and when the terminal voltage of the smoothing capacitor has risen, a power control device decreases the slip of an induction motor in succession, whereby the regenerative power is suppressed to zero.
