An analytical model of multi-sine AC-DC voltage multiplier

This paper proposes an analytical, closed-form multi-sine AC-DC voltage multiplier model and investigates the dependency of input and output power on circuit and device parameters. Comparisons of the proposed model with SPICE simulation results are also provided for validation under various circuit parameters, such as the number of stages and capacitance per stage, and device parameters such as saturation current of diodes. The results suggest a voltage multiplier operating with a continuous wave is not less efficient than one operating with a multi-sine wave. This is in contrast to existing papers that show an entire system which includes both a voltage multiplier and rectenna is more efficient with a multi-sine wave than a continuous wave.
