Annotation: Principle of sinusoidal current consumption is considered. The method to balance output capacitor voltage for three-phase three-level active rectifier in power transition mode to the load is proposed. It shows that capacitor voltage balancing is provided by third harmonic current injection.

Keywords: three-phase three-level active rectifier, power factor corrector, voltage balancing, capacitive voltage divider
