<P>PROBLEM TO BE SOLVED: To reduce the loss of a switching circuit. <P>SOLUTION: A control device for a switching circuit includes a PWM operation unit 25 capable of independently setting each on-duty of a high-side switching element and a low-side switching element in a predetermined switching period. The PWM operation unit 25 includes an energization-ratio operation unit 25a for calculating the integrated value of the on-duty in a plurality of previous switching periods. The PWM operation unit 25 sets the on-duty of the switching element through which a forward current does not flow on the basis of the integrated value of the on-duty calculated by the energization-ratio operation unit 25a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
