Abstract: A power supply system includes a power supply circuit and an output unit. The power supply circuit generates a pulsating voltage. The output unit is to be connected to a pair of electric wires to apply the pulsating voltage to the pair of electric wires. The power supply circuit generates the pulsating voltage such that the pulsating voltage has a full-wave rectified waveform obtained by full-wave rectifying an alternating voltage as a wave alternating between a positive voltage and a negative voltage.

Abstract: In a power supply device, a primary winding of a transformer is connected in series to a main switching element, and is connected in parallel to a series circuit of a resonance capacitor and a sub switching element. A secondary winding of the transformer is connected in series to a series circuit of a rectifying element and a resonance inductor. The capacitance of the resonance capacitor and the inductance of the resonance inductor are each set such that, when the sub switching element is in an on state, the waveform of the voltage that is generated between the first main terminal and the second main terminal of the main switching element takes a protruding curve shape, the voltage being generated due to a resonance phenomenon of at least the resonance capacitor and the resonance inductor.

Abstract: The power supply device includes a converter including a pair of input terminals, a pair of output terminals, a transformer, a capacitor, and a switching device, and a controller for controlling the switching device. The capacitor is electrically connected between the pair of input terminals. The converter further includes a reverse flow preventer for preventing a current from flowing through a closed circuit including the capacitor, a primary winding of the transformer, and the switching device, in an opposite direction to a direction of a discharging current from the capacitor.

Abstract: A wireless power supply system includes a plurality of primary coils and a movable secondary coil. The primary coils excited by the supply of high-frequency current are configured so as to generate an alternating magnetic field by which secondary power is generated in the secondary coil. The resonance characteristics of a resonator including excited primary and secondary coils vary with the movement of the secondary coil within a varying range. The power supply frequency (fn) of the high-frequency current is set to the frequency (fp) corresponding to the intersecting point (P) between a first resonance characteristic line and a second resonance characteristic line, which correspond to the respective two ends of the varying range of the resonance characteristics and are farthest apart from each other.
