Abstract

Multiphase Switched Capacitor Converters (SCC) recently gained attention due to their ability to generate different voltage Target Ratios (TR). One of the reconfigurable multiphase SCC topologies is a binary one. For this SCC, the switched capacitor normalized voltage distribution is binary as the name implies and each capacitor represents a single bit. This paper suggests SCC topologies that are based on non-binary numeral systems -Ternary, quaternary etc. The potential benefits of such SCC topologies compared with binary include reduced switched capacitor stored energy and equivalent resistance. The paper investigates into ternary SCC voltage TR set, possible balanced switching implementation and equivalent resistance calculation using charge flow balance analysis. Multiphase balanced switching allows for essential switched capacitor and peak-To-peak output voltage ripple (or output filter capacitance) reduction.
