3-phase 3-level vienna PFC (Unidirectional)

Description

The Vienna topology is used for high-power 3-phase PFC applications, where a near-sinusoidal input current can be obtained by controlling the voltage level at the DC midpoint. This topology is beneficial when very low THD (Total Harmonic Distortion) of the input 3-phase grid is required.
