Abstract
A DC-DC converter includes a power conversion unit, a load amount detector, a charge detector that detects whether or not a battery is being charged, a switching frequency setting unit, and a switching controller. The load amount detector detects a load amount of the power conversion unit. The switching frequency setting unit sets a switching frequency of a switching element based on the load amount when the charge detector detects that the battery is not being charged, and sets the switching frequency of the switching element to a predetermined value when the charge detector detects that the battery is being charged.
