Abstract—This paper introduces a Switched-Capacitor (SC) DC-AC inverter with cross-connected topology. By cross connecting two charge pump DC-DC converters, the proposed SC DC-AC inverter can achieve small size with a grounded input. Moreover, the cross-connected structure provides the reduction of internal resistance. Therefore, not only small size but also efficient energy conversion can be realized by the proposed inverter. The characteristics of the proposed inverter were investigated by theoretical analysis as well as SPICE (simulation program with integrated circuit emphasis) simulations. The proposed inverter demonstrates higher performances, such as small size and high-power efficiency, than traditional SC DC-AC converters.
