Kertas kerja ini membincangkan dan menghuraikan model analitikal penukar rangsangan voltan (VBC) tersuis-kapasitor (SC) berbilang peringkat untuk sistem penuaian tenaga voltan rendah dan kuasa rendah, kerana galangan keluaran VBC, yang diperoleh daripada model analisis, memainkan peranan penting dalam prestasi VBC. Dalam kaedah yang dicadangkan, kami memberi tumpuan kepada arus yang mengalir ke terminal input dan output setiap peringkat dan model VBC menggunakan frekuensi pensuisan f, kemuatan pemindahan cas CF, kemuatan beban CL, dan parameter kemuatan parasit bergantung kepada proses k. Perbandingan antara hasil simulasi dan pengiraan menunjukkan bahawa model kami boleh menganggarkan impedans keluaran VBC dengan tepat. Model kami berguna untuk membandingkan merit relatif pelbagai jenis SC VBC pelbagai peringkat. Selain itu, kami menunjukkan prestasi prototaip SC VBC dan sistem penuaian tenaga menggunakan SC VBC untuk menunjukkan keberkesanan dan kebolehlaksanaan garis panduan reka bentuk kami yang dicadangkan.

Abstract: This paper discusses and elaborates an analytical model of a multi-stage switched-capacitor (SC) voltage boost converter (VBC) for low-voltage and low-power energy harvesting systems, because the output impedance of the VBC, which is derived from the analytical model, plays an important role in the VBC's performance. In our proposed method, we focus on currents flowing into input and output terminals of each stage and model the VBCs using switching frequency f, charge transfer capacitance CF, load capacitance CL, and process dependent parasitic capacitance's parameter k. A comparison between simulated and calculated results showed that our model can estimate the output impedance of the VBC accurately. Our model is useful for comparing the relative merits of different types of multi-stage SC VBCs. Moreover, we demonstrate the performance of a prototype SC VBC and energy harvesting system using the SC VBC to show the effectiveness and feasibility of our proposed design guideline.
