Abstract

AC current (I1) from a primary power source (1) flows into a primary coil (3a) of a non contact power supply transformer (3) via a power supply line (2) and generates a magnetic field in the vicinity of the primary coil (3a). The magnetic field runs down to a secondary coil (3b) of the non-contact power supply transformer (3) and current (I2) flows in the secondary coil (3b). The current (I2) flows to a power reception unit (4) and a constant DC voltage output V is outputted to an output terminal of the power reception unit (4). The constant DC voltage output V is applied to a load (6) and a large-capacity capacitor (5) to charge the large-capacity capacitor (5). When operation is performed with a maximum load, the charge charged in the large-capacity capacitor (5) is fed to the load (6).
