Experimental Analysis and Comparison of PWM Control Strategies for Shunt Active Power Filter
摘要
Abstract
In this paper, for the better performance of shunt active power filter, some kinds of PWM control strategies used commonly in project are deeply researched, including hysteresis current control strategy, triangular carrier current control strategy and hysteresis 1 strategy based on space vectors, and related simulations are made. The accuracy of various control strategies are analyzed according to the polar figures of current error signals. Design idea about filter which can restrain high harmonic around the switching frequency is proposed according to the analysis of switch signal spectrums. The test platform of shunt active power filter is built, a-dopting ip - iq strategy for harmonic wave detecting and triangular carrier current control strategy for current tracking. The results obtained in simulation and test platform show the rationality of the system design and correctness of algorithm.关键词
