Abstract
An ECU determines whether the ripple current is within a target range (S). When it is determined that the ripple current is not within the target range (NO in S), the ECU determines whether the ripple current is greater than or less than the target range (S). When it is determined that the ripple current is less than the target range (NO in S), the ECU reduces the carrier frequency of the boost converter that is a component of the ripple generating section (S). On the other hand, when it is determined that the ripple current is greater than the target range (YES in S), the ECU increases the carrier frequency of the boost converter (S).
