A power receiving apparatus for receiving first AC power includes a power receiving circuit, a power conversion circuit configured to convert second AC power, which is part of first AC power, into first DC power, a load device configured to consume first DC power, a main power supply circuit configured to supply second DC power, an auxiliary power supply circuit configured to convert third AC power, which is part of first AC power, to supply third DC power, and a control circuit configured to receive power supply from main power supply circuit or auxiliary power supply circuit. The auxiliary power supply circuit is supplied with third AC power via a first portion of power receiving circuit. A first portion has small fluctuations in current and voltage caused by short circuit of inputs of power conversion circuit.
