Synthesis and Analysis of a Simple Inductor-Less DC-AC Inverter

Abstract— To offer AC 100V from a DC 12V cigarette lighter socket, a simple inductor-less DC-AC inverter is proposed in this paper. In the proposed inverter, each capacitor is charged to the voltage of the preceding stage and then stepped-up by the voltage of the preceding stage increasing the voltage of the next stage. By connecting these capacitors in series, the proposed inverter offers AC 100V by using smaller number of capacitors than conventional inductor-less inverters. Therefore, the proposed inverter can achieve small volume and light weight. The feasibility and effectiveness of the proposed inverter are demonstrated by SPICE simulations, theoretical analysis and experiments.

Index Terms— DC-AC inverters, switched capacitor circuits, inductor-less circuits, Fibonacci sequence.
