摘要:
An inductive load driving device includes two inductive loads (20A, 20B) connected to a power source (21), two switching elements (15A, 15B), which are connected in series to the two inductive loads, respectively, their on/off are controlled by a pulse width modulation signal, respectively, and a control device (30), which outputs the pulse width modulation signal to each of the two switching elements, and the pulse width modulation signal is configured such that a rising edge of one pulse of the pulse width modulation signal to be output to one switching element starts between an end point of a rising edge and a start point of a trailing edge of one pulse of the pulse width modulation signal to be output to the other switching element, and a time from a start point of a trailing edge to an end point of the trailing edge of the one pulse of the pulse modulation signal to be output to one switching element does not overlap with a time from the start point of the trailing edge to an end point of the trailing edge of the one pulse of the pulse width modulation signal to be output to the other switching element.
