摘要：
When a PWM signal generating unit (10) sets a duty D of a PWM signal based on command signals (10c), the PWM signal generating unit (10) sets a phase difference φ between each of the PWM signals based on a relation formula of φ (degree)=360 (degree)×D (%)/100 (%), and generates and outputs first PWM signals (10a) and second PWM signals (10b) in which the duty is D (%) and the phase difference is φ (degree). The first PWM signals (10a) and the second PWM signals (10b) are respectively supplied to a first load driving circuit (21) and a second load driving circuit (22) to operate a first motor fan (3) and a second motor fan (4) by a PWM control, respectively.
