碩士 === 國立臺南大學 === 綠色能源科技研究所 === 97 === In this thesis, an inverter circuit embedded with supercapacitor is studied. In the crcuit, a PWM-based voltage-regulated controller is adopted, where an additional current loop is used for minimizing the equivalent output impedance of the inverter in anticipation of increasing the quality of supplying voltage under different load conditions. To validate the performance of the proposed method, a prototype was implemented in the laboratory. From the hardware realization, test results under different scenarios confirm that the proposed method can offer a stable ac voltage for loads while maintain the voltage quality at the expected level, thereby consolidating the feasibility and practicality of the approach for the applications considered.
