Abstract :
The radio frequency conducted electromagnetic interference (10 kHz ∼ 1 MHz) in multirectifier system is discussed. Based on the cable and switch high-frequency model, the simulation about a multirectifier power system is performed. In addition, to characterize the noise generation, a direct calculation in the frequency domain is also performed. The experiment results prove the validity of the proposed method. It is shown that compared with one rectifier system, only the amplitude of the interference is changed, but the frequency content keeps the same.
