Abstract

The extended commutation cell (ECC) is a promising
switching cell that allows for bidirectional energy transport in
two orthogonal directions throughout the cell. By combining the
ECC with a flying capacitor (FC) converter topology, a multilevel converter with a high number of levels can be assembled. This paper presents the analysis of a hybrid converter composed of an arbitrary number of ECCs and a flying capacitor. A 3 kW inverter configuration consisting of two ECCs and a flying capacitor is designed and verified by simulation. The result is a 12-level hybrid converter with equidistant output levels and closed loop control of the capacitor voltages of the ECC and FC. The required number of switches decreases from 22 in a 12-level FC converter to 12 in the proposed hybrid configuration, with the addition of two inductors.
