This paper presents a multilevel modular step-down DC-DC switched-capacitor converter that utilizes soft switching resonant operation. Previous versions of traditional multilevel modular switched-capacitor dc-dc converters (MMSCC) have a low switching device voltage rating. Moreover, capacitor voltage stress increases proportionally as the voltage conversion ratio increments. Significant advantage...
This paper presents a new bidirectional multilevel modular switched-capacitor dc-dc converter for high voltage and high conversion ratio application with low capacitor voltage rating. For the high voltage and high conversion ratio application, high voltage capacitor with good performance will not be available either, like the switching devices. For the traditional multilevel modular switched-capacitor...
This Paper presents a new modular multilevel converter (MMC) concept to achieve high ratio DC-DC power conversion purpose. This converter can be deployed in High-voltage direct current (HVDC) system, or it can be used as a Solid-state Transformer (SST). The proposed converter is flexible, reliable and it possesses scalability and simplicity. The conversion ratio can be regulated by the phase-shifted...
