Abstract
A highly accurate control is achieved in such a way that a timing value is generated from a differential control amount calculation result and a filter calculation result at iteration intervals not exceeding the iteration intervals of the filter calculation and then the timing set value of a driving signal generation circuit is updated by this timing value. A device for controlling a power conversion circuit comprises an AD conversion circuit (), a driving timing value generation circuit (), and a driving signal generation circuit (). The driving timing value generation circuit () includes a control amount calculation circuit () and a digital-digital addition circuit (). The digital-digital addition circuit () generates a driving timing value for a switch of a power conversion circuit. The driving signal generation circuit () receives the driving timing value and generates a driving signal for the switch () of the power conversion circuit ().
