Abstract :
This paper presents a new switched-capacitor multilevel converter (SCMC), which is able to produce any levels at output voltage waveform. This topology can increase the value of input dc voltage sources using the switched-capacitor units. In the proposed SCMC topology, as the numbers of switched-capacitor unit increase, the voltage gain and the number of generated levels is increased. The main merit of proposed SCMC topology is an inherent voltage balancing of capacitors. The proposed SCMC structure is compared with traditional multilevel converters. The comparison results verify that the presented SCMC structure needs lower dc voltages sources, switches, and capacitors. The mathematical analysis of standing voltage on switches and different kinds of power losses are provided. In order to verify the performance of the presented SCMC topology, the experimental results for a typical 13-level converter are provided.
