Abstract
To provide a controller for power conversion circuit which can maintain the detection value of second voltage at the target value of second voltage without depending on feedback control, when the first voltage is varied. A controller for power conversion circuit changes a control value by feedback control so that the detection value of second voltage approaches a target value of second voltage; calculates a control value for control, by correcting the control value based on the detection value of first voltage so as to correct, in feedforward manner, a change of the control value due to a change of the first voltage if correction of the control value is not performed; and controls on/off the switching device based on the control value for control.
