Abstract
A contactless power transmission apparatus includes a transmitter that includes a transmitter coil that supplies electric power to a receiver and a power supply circuit that supplies alternating current power to the transmitter coil. The receiver includes a resonant circuit including a receiver coil that receives electric power from the transmitter and a resonant capacitor connected in series to the receiver coil, a rectifier circuit that rectifies electric power output from the resonant circuit, and a coil connected in parallel to the resonant circuit between the resonant circuit and the rectifier circuit.
