摘要：
This paper presents the analysis and design of a line interactive uninterruptible power supply (UPS) connected to a microgrid through a high step-up/down (bidirectional) dc-dc isolated modular multilevel converter with a high input to output voltage ratio. Resonant switching is used on the MMC to improve overall efficiency of the converter. The input source for this converter is a set of series and parallel batteries and the output of the converter is connected to a microgrid. The proposed converter steps up the input voltage with a 1:15 conversion ratio, and steps down the input voltage with a 15:1 conversion ratio. A transformer is used to both isolate the converter and to further increase the step-up/down ratio.
