Abstract:
A power supply device provided with a main power supply unit that supplies generated predetermined power to an electric load, a current detecting unit, a current indicating unit, an electric storage unit, an auxiliary power supply unit, and a control unit that determines an upper limit current value to be output to the current indicating unit on the basis of at least a condition of the electric load, and controls the upper limit current value such that power supplied from the auxiliary power supply unit to the electric load is converged in a predetermined convergence time when the power supply from the auxiliary power supply unit to the electric load is stopped or reduced.
