Provided are a control device and a control device for a power conversion circuit, said control device having a first control circuit that compensates for detection delays in an analog-to-digital conversion circuit of a second control circuit that compensates for response delays of the integral element and the derivative element of the first control circuit. A first control circuit (), which has a first analog-to-digital converter at the input stage thereof, generates an amount of time, which is a first control amount, on the basis of sampling information for a controlled object, and applies an operation initiation signal to a second control circuit () when a period of time, lasting for the first control amount, has passed from a prescribed reference time. After the operation initiation signal has been input, the second control circuit (), which has a second analog-to-digital converter at the input stage thereof, generates an amount of time, which is a second control amount, on the basis of sampling information for the controlled object, and outputs a switch-switching signal when a period of time, lasting for the second control amount, has passed from the time the operation initiation signal was input.
