摘要：

This article presents a switched-capacitor (SC) volt-age boost converter and its control methods for implementingdc-ac and ac-dc power conversion. The SC converter employsa switched-capacitor circuit augmented with the main convertercircuit to the power source, thus providing unique features thatcannot be attained by the traditional voltage-source inverter(VSI) or boost VSI. The additional features include doubling the area of the linear modulation region and eliminating both the large inductor in the boost dc-dc stage and the large filtering capacitor, which leads to a higher energy density and lower cost. The SC converter concept can be applied to all dc-ac, ac-dc, ac-ac, and dc-dc power conversions. To describe the operating principle and the control, we focus on one example: a bidirectional SC converter for dc-ac and ac-dc power conversion in electric and hybrid electric vehicles. This paper is accompanied by a video demonstrating the change of the modulation functions with the value of A.
