A new control strategy is developed for a four-level flying capacitor multilevel inverter to function as an active power filter (APF). This employs space vector modulation (SVM) according to capacitor voltage values at each level. It also applies a modified predictive current control law taking into account the derivative of the reference current. Simulation study has shown that the proposed scheme leads to high performance harmonic current compensation for both steady and transient state
