Abstract
A power supply apparatus includes a first circuit, a second circuit, a control unit, and an anomaly determination unit. The first circuit includes a first resistor portion, and is provided in parallel to the first switching element. The second circuit is provided between a first conduction path and a second conduction path. The first circuit is configured such that a current flows from the power supply unit to the load via the first resistor portion. The second circuit is configured such that a current flows from the first conduction path to the second conduction path when in a current conduction state. The anomaly determination unit determines an anomaly based on a voltage of the first conduction path when the second circuit is in the current conduction state.
