Patent ID: 7317304

Claim:
An inductive load driving device, comprising: a first motor and a second motor connected to a power source; a first switching element, which is connected in series to the first motor, and permits conduction of the first motor in an on state; a second switching element, which is connected in series to the second motor, and permits conduction of the second motor in an on state; and a control device, which outputs a first pulse width modulation signal to the first switching element, outputs a second pulse width modulation signal to the second switching element and controls on/off of the first switching element and the second switching element, wherein a rising edge of one pulse of the second pulse width modulation signal to be output to the second switching element starts between an end point of a rising edge and a start point of a trailing edge of one pulse of the first pulse width modulation signal to be output to the first switching element, and a time from the start point of the trailing edge to an end point of the trailing edge of the one pulse of the first pulse width modulation signal to be output to the first switching element does not overlap with a time from a start point of a trailing edge to an end point of the trailing edge of the one pulse of the second pulse width modulation signal to be output to the second switching element.
