Common-Mode Reduction for ANPC With Enhanced Harmonic Profile Using Interleaved Sawtooth Carrier Phase-Disposition PWM

Autor: Gabriel H. P. Ooi, Ziyou Lim, Ali I. Maswood

Publikováno v: IEEE Transactions on Industrial Electronics. 63:7887-7897

Multilevel active neutral-point-clamped (ANPC) converter is popularly known for its higher medium voltage drives up to 6.9 kV. However, common-mode voltages (CMV) are generated when using the well-established carrier-based pulse width modulation (PWM

Grid connected three‐phase multiple‐pole multilevel unity power factor rectifier with reduce components count

Autor: Gabriel H. P. Ooi, Ziyou Lim, Ali I. Maswood

Publikováno v: IET Power Electronics. 9:1437-1444

This study presents a simple design and cost-effective rectifier topology based on five-level multiple-pole structure. Better efficiency and low grid current total harmonic distortion is achieved with the constant low switching frequency operation. T
