Evaluation of the Impact of Low Parasitic Losses on Power Conversion PCB Design for Bio-Power Generation

Bio-power is a kind of renewable energy made of materials derived from microorganisms which perform the chemical action to generate weak voltage and current, and how to use this energy efficiently is closely related to the design and implementation of the application circuit. In this paper, the layout design of the circuit board used for bio-power generation is taken as the starting point, and the parasitic capacitance and static current on the circuit board are improved by the most appropriate layout method, and the results are tested and analyzed by implementing this circuit. In this circuit design, the existing ICs on the market are used for energy harvesting of bio-power generation. The actual harvesting power circuit is designed and implemented by appropriate layout techniques to maintain the quiescent current at the ideal value of the IC itself and to improve the parasitic capacitance on the circuit board. Finally, a series analysis of two type circuit implemented are carried out to confirm the layout process proposed in this paper. From these results shown that the proposed method can keep the quiescent current of the circuit within the ideal range so that the error does not exceed 10%.
