中文摘要:

详细分析了基于瞬时无功功率理论的解耦整流策略与传统双闭环非解耦控制策略的不同。从控制的简易程度、整流后直流侧电压的稳态和动态性能等方面进行对比分析。非解耦策略结构简单,但电流内环为交流环,传统PI不能消除电流静差；解耦策略双闭环均能消除静差,电压稳态性能好,但控制复杂。两者均能实现功率因素为1。实验结果证明了分析的正确性。

英文摘要:

Make a detailed analysis of the decoupling rectification strategy based on instantaneous reactive power theory and non decoupling control strategy based on traditional double closed loop. Comparative analysis are made from complex of control, rectifier DC voltage steady-state and transient stability etc.. Non decoupling strategy have advantages of simple structure, but the inner current loop based on traditional PI control can not eliminate the alternating current static error; Decoupling control can eliminate the both inner and outer loop static error and voltage steady-state performance is good,but control is complex. Both strategy can make the power factor be 1. The experimental results prove the correctness of the analysis.
