“…However, the conversion ratios of the conventional SIDO converter reported in reference ( 8) are only 2x and 3x. Chen et al proposed an SC SIDO converter employing pseudo-three phase swap-and-cross control (10) . By connecting series-parallel type converters (11) in parallel, the conventional converter reported in reference (10) achieves step-up and step-down conversion.…”

“…The proposed SIDO converter consists of 15 transistor switches and 3 capacitors. Unlike conventional SC converters (6)(7)(8)(9)(10)(11) , the proposed converter can offer nine kinds of two stepped-up/ stepped-down outputs: V in /3 and 2V in /3, V in /3 and V in , 2V in /3 and V in , V in /2 and V in , V in and 3V in /2, V in /2 and 3V in /2, V in and 2V in , V in and 3V in , and 2V in and 3V in . This paper also presents a novel analysis method to estimate properties of the SC SIDO converters, because few studies have been done on the theoretical analysis of the SC SIDO converters.…”

In this paper, we propose a single-input dual-output (SIDO) DC-DC converter designed by switched capacitor (SC) techniques. Unlike conventional SC converters, the proposed converter can provide nine kinds of two steppedup and/or stepped-down output voltages without changing circuit topology. This paper also presents a novel analysis method to estimate properties of the SC SIDO converters, because few studies have been done on the theoretical analysis of the multi-output SC converters. Unlike the traditional state-space averaging method, the proposed method can derive the power efficiency and output voltages without complex matrix calculations. The simulation program with integrated circuit emphasis (SPICE) simulation shows the following results: (1) more than 82% efficiency is obtained over a range of output power from 0.1W to 1W with conversion ratios of 1/2 and 3/2 and (2) the proposed analysis method will be helpful to estimate the power efficiency and output voltages of the SC SIDO converter, because theoretical results are in good agreement with SPICE simulated results. Furthermore, experiment on a breadboard shows the validity of the proposed SC SIDO topology.
