To automatically perform confirmation and adjustment of parameters for checking a model type of a magnetic bearing body and controlling the magnetic bearing body, the magnetic bearing body 20 is provided with a resistor 412 for identifying a model type and a body EEP-ROM 411 in which the model type and various characteristic values are stored. A prioritization software analyzes a supplier’s bidding participation history and bidding competitiveness history from the bidding data collected for all prior auctions in which the supplier participated or was requested by the auction coordinator to participate. The spaced ports are sequentially straddled for initial setting and a subsequent release using a predetermined applied pressure. Thus when an IG short involving the predetermined terminal occurs, the drive voltages are changed by the switching control circuit sensing the change in the feedback voltage. A lowpass andor a highpass filter for the alternating current signal is connected upstream from the at least one primary winding.
