Abstract:
A switching frequency setting unit sets switching frequency of a switching element, based on both the temperature of a cooling medium which cools a DC-DC converter and the temperature of a switching element of the DC-DC converter. A switching controller controls the voltage conversion ratio of the DC-DC converter by controlling switching operation of the switching element at the set switching frequency.
