Abstract
A range calculator () calculates an operation value range, which is range of an operation value tor controlling a duty cycle of a chopper circuit () based on an input voltage and output voltage command value of the chopper circuit (). A chopper circuit control device () controls the duty cycle of the chopper circuit () by using an upper limit value of the operation value range when an operation value is greater than or equal to the upper limit value of the operation value range, by using the operation value when the operation value is within the operation value range, and by using a lower limit value of the operation value range when the operation value is less than or equal to the lower limit value of the operation value range.
