Abstract :
This paper first established a mathematical model for the split-capacitor three-phase active power filter. Based on the precise mathematical model, it then proposed a control strategy under dq0 coordinate for the DC voltage control of APF, to control the d axis current for DC total voltage stability, to control the q axis current for DC voltage balance. Finally, simulation and experiment result proved the correctness and effectiveness of the control strategy.
