Abstract
A power receiving apparatus receives a bus voltage from a power supply apparatus via a cable, and supplies the bus voltage to a load circuit. A power receiver side controller receives, as a power supply, a voltage Vof a bus line that is more toward a bus switch. The power receiver side controller is capable of communicating with a power supply side controller of the power supply apparatus. Furthermore, the power receiver side controller determines the voltage to be supplied based on a negotiation, and controls the bus switch. A short circuit detection circuit detects a short circuit of a bus line that is more toward the load circuit side than the bus switch.
