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