摘要
When multiple distributed converters are integrated, the high frequency harmonics will randomly accumulate at the point of common coupling (PCC). This paper proposes a new fast global synchronous discontinuous pulse width modulation (GSDPWM) method of three-phase inverters to effectively attenuate the high frequency current harmonics at PCC. Firstly, the basic principle and the realization method of GSDPWM for three-phase inverters are explained, which can be employed for different modulation types. Then a fast calculation method, which can equally derive the minimized total harmonic distortion (THD) of total current, is proposed to release the calculation burden. Finally, MATLAB simulations and experimental results are presented to verify the performance of GSDPWM.
