This paper presents a novel loss balancing modulation method for more evenly distributing semiconductor losses in multilevel active neutral-point-clamped (ANPC) converters. The presented method is achieved by optimally utilizing the redundant switching states of space vector pulse width modulation (SVPWM) in ANPC converters. A comparison of the effect of losses distribution between the proposed loss...
This paper presents the application and losses analysis of three-level active neutral-point-clamped (ANPC) back-to-back converters in a doubly-fed induction generator (DFIG) wind energy conversion system (WECS). A phase-shifted sinusoidal PWM strategy with the advantages of doubling the apparent switching frequency and better balancing loss distribution among switches is employed for the ANPC back-to-back...
