Improved design of switched capacitors for power electronics converters

This paper brings the improved design of switched capacitors for power electronics converters. The desired value of capacity is obtained by switching between two capacitors with a specific duty cycle. The old method for calculating the value of the switched capacity and the duty cycle is based on energy conservation. This method, however, as shown below, does not provide a precise result. For this reason, a new averaging method is derived. The practical use of the switched capacitors is shown on a two-phase load, with auxiliary phase current advancing.
