本文描述了一种基于直接功率控制的电压源脉宽调制（PWM）整流器-逆变器的新型控制策略。该策略的关键是根据瞬时功率误差直接选择 PWM 整流逆变器的开关状态。从理论上分析了PWM整流逆变器的瞬时功率与开关状态之间的关系，这对于构建开关状态表至关重要。使用 1.6 kW 原型机通过多次实验测试检验了所提出技术的有效性。结果，通过所提出的方法实现了单位功率因数操作，并且在平衡和不平衡电源条件下输出电流被证实为正弦波形，没有大的失真。
This paper describes a novel control strategy of direct power-control-based voltage-source pulsewidth modulation (PWM) rectifier-inverter. The key of this strategy is direct selection of a switching state of the PWM rectifier-inverter on basis of instantaneous power errors. A relationship between the instantaneous power and the switching state of the PWM rectifier-inverter is theoretically analyzed, which is essential to compose a switching-state table. Effectiveness of the proposed technique is examined through several experimental tests, using a 1.6-kW prototype. As a result, unity power factor operation is achieved by the proposed method, and the output currents are confirmed to be sinusoidal waveforms without large distortion under balanced and unbalanced power-source condition.
