摘要
Abstract
The basic control rule applied to three-phase four-switch inverters（TFSI） for outputting three-phase balanced voltages is revealed.Based on this rule,a novel space vector pulse width modulation（SVPWM） algorithm is proposed in order to control the three-phase four-switch shunt active power filter（TFSSAPF）.By introducing an advanced coordinate transform method,the proposed algorithm makes sure the basic voltage vectors to be on the coordinate axes in the two-phase stationary coordinate system,so that it only needs the four arithmetic operations of two line voltages to accomplish the selection of the basic voltage vector and the calculation of its function time.The proposed algorithm has the advantages of less detection units,less computation and higher accuracy than the traditional ones.As the output voltage vectors of the TFSSAPF have no zero-vectors,a so-called ＇five segment type＇ algorithm is presented to synthesize the zero-vectors by forcing the durations of the voltage vectors which are equal in extent and opposite in phase equal to each other,which has the advantages of simply control logic and low harmonic contents of the output voltages.Simulation and experiment results show the validity and feasibility of the proposed algorithm.关键词
