NPC three-level series active power filter with neutral-point voltage self-restraining

摘要：

　　Series active power filter(SAPF)improves power quality as a key technology,which has been highly valued and widely used at present.NPC(neutral point clamped)three-level SAPF enables to compensate harmonic voltage in the field of high voltage,but traditional NPC three-level SAPF has a problem of neutral-point voltage excessive fluctuation which will cause switch devices damage.In order to solve this problem,a NPC three-level SAPF with neutral-point voltage self-restraining function is proposed.A controllable voltage source will be put in series between the neutral point of the DC-side capacitors and point O in traditional NPC three-level SAPF.To obtain better control effects,sliding mode control method is used to control the compensation voltage generated.Neutral-point voltage will be compensated in the real-time.Simulation results show that the proposed SAPF has good performances.
