ELECTRIC POWER SUPPLY SYSTEM AS WELL AS A FIXED BODY AND MOBILE BODY THEREFOR |
摘要 |
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 (24). The fixed body (10) includes: a first power-transmitting electrode (12) and second power-transmitting electrode (13); and an AC power supply (11) to supply AC power to the first power-transmitting electrode (12) and second power-transmitting electrode (13). The movable body (20) includes: a first power-receiving electrode (21 a) and second power-receiving electrode (21 b) to form a first coupling capacitor (30) and a second coupling capacitor (31), respectively, by being placed in a manner opposed to and not contacting corresponding ones of the first power-transmitting electrode (12) and second power-transmitting electrode (13) while facing one side of an interface, the one side not being faced by these power-transmitting electrodes, and a first capacitor (22a) and first coil (22b) connected to one another in parallel between the first power-receiving electrode (21 a) and second power-receiving electrode (21b). The AC power supply (11) transmits power to the load (24) via the first and second coupling capacitors under a condition that causes parallel resonance between the first capacitor (22a) and first coil (22b). |
