  "textContent": "An operation processing unit (3A) computes an amount of operation for adjusting electric power supplied to a load (5). A signal generator (4) computes, based on an amount of operation, the number of switch elements to be turned on among switch elements (S1) to (Sn) and a duty ratio to be set for the number of switch elements to be turned on and generates, based on the determined number of switch elements and duty ratio, a signal for driving at least one of the switch elements (S1) to (Sn). The signal generator (4) includes a correction value operation unit that obtains a correction value based on a difference of an on-pulse width between a shunt current flowing through a corresponding one of the switch elements and a shunt drive signal for driving the corresponding one switch element, and a corrector that corrects, based on the correction value, an amount of operation output from the operation processing unit.",
