Performance Evaluation and Analysis for Resonant Switched Capacitor Converter

In this paper, a new method helps compare and analysis different topology is proposed. Also, a new method that can analyze and derive the minimum device power loss for the resonant switched capacitor topology is developed. By applying total semiconductor power loss index (TSLI), the optimum total die size needed for the specific topology with fixed power level and switching frequency can be calculated. Thus, the minimum device power loss can be reached at same time. Besides, TSLI can also help to determine which topology has a lower semiconductor device power loss when operating under same condition.
