摘要/Abstract

摘要： 提出了一种多开关表直接功率控制策略,通过分析各电压矢量对瞬时功率、上下电容电压差值升降率的影响,给出了以瞬时功率和中点电位为调节目标的开关表;设定了控制目标的优先级,系统能够根据瞬时功率和中点电位的误差情况调整控制目标,并从多开关表中选择合适的电压矢量。利用仿真和实验将该策略与单开关表的直接功率控制策略相比较,结果表明,采用该策略的系统具有更好的动态和稳态性能。

Abstract: A direct power control(DPC) strategy based on multiple switching tables was proposed. In the work, the switching tables for regulating instantaneous power and neutral-point potential were given, after analyzing the voltage vectors’ influences on the gradient of instantaneous power and the voltage difference between the two capacitances. The control objective was able to adjusted according to the errors of instantaneous power and neutral-point potential after setting the priority of the control objective, and the suitable voltage vector could be selected from the given switching tables.Both the simulation and experiment are established to compare the proposed strategy to the single switching table DPC, the results show that the proposed strategy has a better dynamic and steady-state performance.

Key words: Vienna rectifiers, switching table, direct power control(DPC), neutral-point potential
