Design and Analysis of a Generalized Dual Fibonacci Converter Using Improved Charge Reusing Techniques

Abstract:

For energy-harvesting systems utilizing thermoelectric energy, a dual Fibonacci converter using power saving techniques is proposed. Compared with conventional converters, the proposed converter can provide higher output voltages without magnetic components. The output voltage of the proposed converter is expressed by the k-step (2, 3, 4 ...) Fibonacci numbers. Furthermore, a novel control technique is proposed to utilize the energy stored in stray parasitic capacitances effectively. The result of simulation program with integrated circuit emphasis (SPICE) simulations shows that the proposed converter can provide higher output voltages than conventional converters. Furthermore, more than 8.4% of power efficiency is improved by the proposed technique.
