ABSTRACT:
AC input voltage is lowered at a transformer, rectified at a rectifying circuit, then smoothed at a smoothing circuit, and thus produced DC voltage is supplied to an inverter which drives a motor. The rectified DC voltage is provided to a DC/DC converter to generate power supply for a magnetic bearing, and DC power supply for controlling the magnetic bearing is generated at a DC/DC converter. During the power failure regenerative electric power from motor is provided to DC/DC converter to produce power voltage for the magnetic bearing, and DC voltage for controlling the magnetic bearing is provided from DC/DC converter.
