Three-phase Vienna rectifier

Three-phase power is often used by high power industrial applications. To improve overall quality and minimize harmonic currents power factor correction (PFC) is often required as many of the forward loads are DC – for example electric vehicle (EV) battery charging. The Vienna rectifier power topology is often the preferred choice as it operates in continuous conduction mode (CCM), has inherent multilevel switching (three level), and reduced voltage stress on the power devices.
