Carrier modulated pulse width modulation for adjusting the distortion spectrum of clock-type power electronics

摘要

The present invention relates to a control method of a power electronic device system 200, wherein the power electronic device system 200 includes at least two power semiconductor switches 243 and 244, and is provided by the first control unit 230. Controlled according to pulse width modulation, the pulse width modulation is performed according to a dynamically changing clock signal 236, and each clock signal uses a predetermined target spectrum by the second control unit 210 at one time point. Is calculated. Furthermore, the present invention relates to a corresponding system.
