Abstract
A power supply system and a connector, which can suppress occurrence of crosstalk between a power supply wire, and a control wire and an earth wire in a charging cable that includes the power supply wire, the control wire and the earth wire at the time of connecting a power supplying device with a vehicle having a power storage device to be supplied with power from the power supplying device via the power supply wire and the earth wire to be used for supplying power and the control wire for transmitting a control signal to be used for power supply control of the power storage device, are provided. The ratio of the winding number of a primary coil connected with at least one of the control wire and the earth wire to the winding number of a secondary coil connected with a communication unit that sends and receives a communication signal is set at 1/N (N>1) in a system which satisfies VnC>VnL or is set at N (N>1) in a system which satisfies VnC<VnL.
