Abstract
A plurality of pickup coilsA andB are provided, resonance capacitorsA andB forming resonance circuitsA andB resonating at the frequency of an inductive pathare respectively connected in series with the pickup coilsA andB, and the resonance circuitsA andB are connected in series. Further, the resonance circuitsA andB are respectively provided with rectifier circuitsA andB for rectifying voltages generated by the resonance circuitsA andB. The rectifier circuitsA andB are connected in parallel and feed power to a load. Moreover, a switchis provided to switch a connected state and an open state between the resonance circuitsA andB, and a voltage controlleris provided to control an output voltage applied to the load, by controlling the switch
