摘要:
针对传统的三相电压型 PWM 整流器直接功率控制存在无功功率失控区和直流侧输出电 压波动大等缺点,提出了一种双开关表控制的直接功率控制策略。根据各个扇区内不同开关矢量 对有功功率与无功功率作用的大小,设计了快速、慢速两种开关表。有功功率滞环比较器采用三电 平控制,系统根据当前滞环输出结果和控制幅度的值选择快速或慢速开关表,产生开关信号驱动主 开关进行直接功率控制。仿真和实验结果表明双开关表直接功率控制策略消除了无功功率的失控 区,改善了系统的动态特性。

Abstract:
 There are some deficiencies that reactive power has incontrollable area and DC output voltage has large fluctuationin controlling of voltage source PWM rectifier. Double switching sector table direct power control strategy was used to solve some shortcomings of traditional control strategy applied in voltage source PWM rectifier. Fast and slow speed switch tables were set according to different switching vectors for active and reactive power control range within each sector. Active power hysteresis adopted the three - level hysteresis comparator,and switching signal were generated to drive the main switch for direct power control based on the result of the hysteresis output and the span of control in the system. Both the simula-tion analysis and experimental results suggest that the improved direct power control strategy eliminates the incontrollablearea of reactive power and improves the dynamic characteristics of the system.
