Abstract
To provide a power supply unit configured to determine the boundary between the operation modes (continuous mode and discontinuous mode) of a converter with high accuracy. The power supply unit is a power supply unit wherein the controller controls a value of output current of the power supply by controlling a duty ratio by switching the second switch; wherein the controller detects the current value of the reactor acquired by the current sensor, at a frequency of at least n (n is an integer of 2 or more) times in a cycle of the switching.
