摘要： A switching device and a method of operating a switching power element are disclosed for generating a train of drive pulses (D1 to D32) in a basic pattern for a repetition cycle time (T to TF) having leading time intervals (Th1 to Th3, Th1′ to Th3′), associated with leading edges (a1 to a32) of the drive pulses, and trailing time intervals (Tl1 to Tl3, Tl1′ to Tl3′), associated with trailing edges (b1 to b32) of the drive pulses, which are different from each other, whereby switching frequencies and associated harmonics, resulting from the leading edges and the trailing edges of the drive pulses, are diffused. A diffusion frequency, representing an inverse number of the repetition cycle time for the basic pattern is set to be higher than an audible frequency.

摘要： A switching device 30 and a related operating method are disclosed for generate a train of drive pulses under a basic pattern for a repetition cycle time T. The train of drive pulses has leading edges shifted from basic time periods T1 by shift amounts Φ0 to Φ02, respectively, which are different from each other, whereby switching frequencies, occurring based on the leading edges of the drive pulses, are spread. A spread frequency, which is a inverse number of the cycle time T of the basic pattern, is set to be higher than an audible frequency.
