Abstract
Provided is a power supply system which makes it possible to stably supply power regardless of changes in placement of electrodes. The power supply system for supplying power to a load (). The fixed body () includes: a first power-transmitting electrode () and second power-transmitting electrode (); and an AC power supply () to supply AC power to the first power-transmitting electrode () and second power-transmitting electrode (). The movable body () includes: a first power-receiving electrode () and second power-receiving electrode () to form a first coupling capacitor () and a second coupling capacitor (), respectively, by being placed in a manner opposed to and not contacting corresponding ones of the first power-transmitting electrode () and second power-transmitting electrode () while facing one side of an interface, the one side not being faced by these power-transmitting electrodes, and a first capacitor () and first coil () connected to one another in parallel between the first power-receiving electrode () and second power-receiving electrode (). The AC power supply () transmits power to the load () via the first and second coupling capacitors under a condition that causes parallel resonance between the first capacitor () and first coil ().
