PROBLEM TO BE SOLVED: To provide a signal generation circuit capable of substantially making the minimum unit of a value to be respectively set in m generation parts (m is a natural number of 2 or more) for periodically generating a PWM signal corresponding to a set value become smaller than the actual minimum unit, and to provide a voltage conversion device and a signal generation method.SOLUTION: A CPU 11 specifies a settable value being the closest to the total sum for n periods of a target value every n periods of PWM signals respectively generated by m generation parts SG1, SG2, ..SGm, determines m set values for n periods on the basis of a quotient Q and a remainder R obtained by dividing the specified settable value by a product of m and n, and respectively sets the m set values in the generation parts SG1, SG2, ..SGm by phase-classified interruption processing different in each period of the PWM signal.SELECTED DRAWING: Figure 1 |
