Abstract
A control device for a step-up converter which controls the step-up converter connected between a load and a DC power source, the control device includes a voltage control unit, a current command generation unit, a duty estimator, and a pole zero cancellation control unit. The voltage control unit performs a control arithmetic operation on the basis of a calculated value, obtained by performing a proportional arithmetic operation and an integration arithmetic operation on a difference between a voltage value on the load side and a voltage command value, and a value generated by the pole zero cancellation control unit. The current command generation unit generates a reactor current command value on the basis of an arithmetic result of the voltage control unit and a reciprocal of a duty estimation value.
