The fundamental principle is to divert the ripple power from DC-link to another energy storage component with long lifetime by an extra active circuit. Usually, single-phase AC/DC converters are divided into voltage source converters and current source converters.

When compared to the much more common voltage-source inverter (VSI), the current-source inverter (CSI) is rarely used for variable speed drive applications, due to its disadvantages: the need of a constant DC-link current, typically realized with a front-end converter, and the need for reverse-voltage blocking (RVB) devices, typically
