本論文提出具電壓模式控制之Dickson切換式電容多階層逆變器，藉由獨特的切換式電容充放電技術，以及閉迴路電壓模式控制方法，可實現輸出15階層電壓，提供輸出為110 Vrms有效值電壓及60 Hz頻率，以及提供100 W的輸出功率，此外，能有效減少電容電壓漣波及減少輸出的總諧波失真。此逆變器因為無需使用磁性元件，如：電感或變壓器等，因此能減少體積及重量，實現高功率密度，且具有電容電壓自我平衡能力等優勢。相較於其他切換式電容多階層逆變器，此電路具有以下優勢：1) 與串並式(Series-parallel)切換式電容多階層逆變器比較，在使用相同電容數量下，有較高的升壓倍率及較高的輸出電壓階層數，2) 與指數型及斐波那契(Fibonacci)數列型切換式電容多階層逆變器比較，使用的功率開關有較低的電壓應力。在本論文裡所提出的多載波正弦脈波寬度調變器及電壓模式閉迴路控制電路皆在MATLAB/Simulink模擬中驗證其可行性。最後，在實驗中，驗證此閉迴路系統皆能在電阻性及電感性的負載情形下，進行輕重載及變載實驗，以及在輸入電壓改變情形下，皆能維持輸出有效值電壓為110 Vrms及60 Hz，在輸出功率為100 W的情形下，輸出總諧波失真約為2.3 %，以及效率約為94.1 %。

This thesis presented the voltage mode control for a Dickson switched-capacitor multilevel inverter (SCMLI). With the unique switching capacitor charging and discharging technique and closed-loop voltage control, a 15-level voltages at the output can be realized, providing a 110 Vrms output voltage and 60 Hz frequency and 100 W output power. In addition, the capacitor’s ripples and output total harmonic distortion (THD) can be effectively reduced. This inverter does not require magnetic components, such as inductors and transformers, so the size and weight can be reduced, and a high power density can be realized. And, this inverter has a voltage self-balancing ability. Compared to the other SCMLIs, this inverter has the advantages: 1) a relatively high boost ratio with the same number of capacitors compared with series-parallel solutions, 2) a relatively low voltage stress of the switches compared with exponential and Fibonacci solutions. The presented multicarrier sinusoidal pulse width modulator and closed-loop circuit were verified by MATLAB/Simulink simulation. Finally, a hardware prototype was built to verify the closed-loop voltage control for a Dickson SCMLI in the experiments with resistive and inductive loads, respectively. An output voltage of 110 Vrms and a frequency of 60 Hz can be realized with various loads and input voltages, respectively. The inverter has a THD of 2.3 % and an efficiency of 94.1 % at the load of 100 W.
