An adaptive pulse width modulation (PWM) strategy is proposed for four-switch three-phase inverter (FSTPI) to improve the performance and simplify the algorithm. The FSTPI has a split DC-link and one phase of the AC load is connected to the neutral point. The conventional space vector PWM has a limited performance in the low-frequency region since the phase currents are unbalanced due to the neutral-point...
Neutral-Point voltage fluctuation is one of the most important issues of NPC three-level inverters. In this paper, two kinds of control region are proposed to evaluate the control effect of neutral-point voltage balancing schemes. Basing on hysteresis control strategy, the paper analyses the control region in SPWM and SVPWM respectively and finds their relationship, it also finds the relation between...
