Abstract :
In this paper, the conducted EMI paths in PWM rectifier of electromagnetic interference (EMI) in voltage source rectifier (VSR) are investigated, then a novel chaotic space vector pulse width modulation (SVPWM) scheme is applied to PWM rectifier. Such an approach uses chaotic sequence with continuous power spectrum to suppress the peaky switching harmonics, hence it fundamentally restrains EMI caused by harmonics. Compared with the conventional fixed-frequency PWM rectifier, the proposed scheme can not only significantly reduce harmonic peak of output voltage at switching frequencies, but also keep the rectifier operating performances at transient and steady state unaffected. MATLAB / SIMULINK simulation results verify the validity.
