Title: POWER RECEIVER AND POWER TRANSMISSION SYSTEM
Abstract:
Provided are a power receiver whereby power supply balance can be improved, and a power transmission system. A power receiver of the present invention includes: a first secondary resonance coil; a rectifying circuit that performs full-wave rectification with respect to alternating current power outputted from the first secondary resonance coil; a line connected to the output side of the rectifying circuit; a pair of output terminals connected to the line; a first smoothing capacitor that is provided between the rectifying circuit and the pair of output terminals; a second smoothing capacitor that is provided between the first smoothing capacitor and the pair of output terminals; a switch inserted in series into the line between the first and second smoothing capacitors; an inductor inserted in series into the line between the first smoothing capacitor and the switch or between the switch and the second smoothing capacitor; and a drive control unit that drives the switch with a first PWM drive pattern.
