Abstract

In this paper, a modified method named reconstructed carrier quasi-trapezoidal pulse width modulation (RC-qTPWM) is proposed to improve the DC voltage utilization ratio, decrease the line voltage total harmonic distortion (THD), and solve the power imbalance among H-bridge units. The modulation method is based on two steps. In the first step, the quasi-trapezoidal wave obtained by an intercepting sine wave is used as the modulation wave to improve the DC voltage utilization ratio. In the second step, the carrier arrangement of the phase disposition is reconstructed to achieve a power balance among the H-bridge units. Carrier reconstruction is achieved by shifting a single triangular carrier in the horizontal and vertical directions. Through simulation and theoretical analysis, the selection method of the optimal sine coefficient δ and the principle of the carrier reconstruction are expounded, which shows that the optimal sine coefficient δ is 0.58 and that the power balance can be achieved within 3Tc. When compared with conventional TPWM methods, this modulation method has a higher DC voltage utilization ratio, a better efficiency, a smaller line voltage, a reduced current THD, and better power balance performance. Experimental results verify the correctness of the simulation and theoretical analysis, and the feasibility of the RC-qTPWM method.
