Abstract

Based on the double three-phase bridge AC-DC PWM converter topology, this paper takes the series-parallel compensated UPS as APF to compensate harmonic in power system. Corresponding control strategies are studied. The decoupling control strategy of dq axis dual-loop based on direct current control scheme is used. To the problem of input voltage imbalances and harmonic voltage in non-ideal power supply, a control method with an input harmonic voltage feed-forward in dq0 frame is taken. The experimental results prove that the series-parallel compensated UPS can effectively improve the power quality.
