Abstract

In this paper, the authors propose a new space vector pulse width modulation (SVPWM) algorithm based on non-orthogonal coordinates for N-level inverters. First, it is pointed out that classical αβ coordinates-based SVPWM has many shortcomings because of improper coordinate choice. Then, a non-orthogonal coordinates-based SVPWM is proposed to solve these problems. The proposed algorithm can easily identify which sector the reference space vector falls in and conduct simple operations to find the duty cycle of each vector. Finally, it is verified that the proposed SVPWM is actually a pulse-width modulation (PWM) technology based on line voltages.
