摘要：<P>PROBLEM TO BE SOLVED: To reduce influence of noise on peripheral apparatuses accompanied with PWM control including a start period and a period before stop. <P>SOLUTION: A frequency diffusion control section 24 repeatedly switches a carrier frequency fc to five stages to disperse a frequency component of switching noise accompanied with PWM control; however, during a period with a low duty ratio, such as a start period and a period before stop, stops frequency diffusion control and controls the carrier frequency fc to be constant. <P>COPYRIGHT: (C)2012,JPO&INPIT
