Abstract

This paper describes three ideal topologies of switched-capacitor converters, taking into account integration considerations and multiple DC voltage ratios. First, the ideal continuous capacitor idea is described, and then a Matrix of Capacitors configuration is proposed. This configuration is based on rectangular matrices of capacitors charging and discharging in transposed configuration for achieving the input/output DC voltage ratio. The third topology is The General Transposed Series-Parallel configuration. This is a modification with a discrete number of capacitors. The configuration is based on parallel brunches of series capacitors in the charging state and series elements of parallel capacitors in the discharging state. This topology is suitable for fine tuning in the DC voltage ratios. The Matrix and the Transposed Series-Parallel topologies are compared for an input/output ratio of 1.1. In the later topology, fewer components are required for the assumed ratio. Simulation is performed for 3 elements in the Transposed Series-Parallel topology, where each element consists of two dual identical capacitors for the elimination of external large capacitors.
