Abstract
In this thesis, a compact, highly efficient, voltage doubler (VD) is introduced for use in energy harvesting (EH) and wireless power transfer (WPT) applications. The design utilizes a harmonic termination network based on inverse class-F configuration. The inverse class-F configuration was constructed by a mixture of transmission lines and discrete components to reduce the size. Furthermore, the structure enhances efficiency by shaping the current and voltage waveforms to be square and semi-sine waveforms, respectively, thereby reducing the overlap between the voltage and current waveforms. Therefore, at an input power of 12 dBm, a peak conversion efficiency of 80.7% was achieved at a frequency of 2.45 GHz compared to the conversion efficiencies of 80.2% and 80.4% obtained by (Z. He et al.) (2020) and (F. Zhao, et al.) (2019) respectively. Moreover, a fractional bandwidth equal to 24.5% corresponding to 600 MHz of bandwidth was obtained at an RF-DC conversion efficiency greater than 60%. While the saturated DC output voltage equals 6 V using a load resistance equals to 2.45 kΩ. Lastly, the proposed layout has overall dimensions of 12.9 × 6.4 mm2. The Proposed layout is superior to the PCB sizes proposed by (F. Zhao, et al.) (2019) and (G. T. Bui) (2023) which have dimensions of 30 × 19 mm2 and 40 × 23 mm2 respectively.
