Abstract

The current tracking control strategy is one of the key technologies influencing compensation performance of active power filter.As for the four-leg APF applied to three-phase four-wire power system

the mathematical model of the main circuit is set up firstly and a kind of deadbeat current tracking control strategy is proposed.The command current value of the next moment can be predicted by the control strategy at the moment of present sample and the reference voltage is calculated.By using space vector pulse width modulation

the bridge arm switching signal is obtained by the use of space vector pulse width modulation algorithm with purpose of current track and control.The correctness and feasibility of the method is verified by the simulation result.
