The main circuit topology of a three-level active power filter(APF) and its mathematical model in three-phase three-wire system were established.Analysis was made to the simplified three-level space vector control algorithm and the capacitor midpoint potential control method.Results of the experiments show that the system based on the simplified three-level space vector pulse width modulation(SVPWM) algorithm can obtain good harmonic compensation in the APF application.It is suitable for digital hardware realization and has better application prospect.
