本文利用建構電路之數學模型，推導具飛馳電容之多階層升壓型直流直流轉換器電路之轉移函數。以推導(2+1)階層與(3+1)階層電路之轉移函數為例，發現不管具飛馳電容之多階層升壓型直流直流轉換器電路為幾階層，其轉移函數皆可透過參數設計，簡化為分母二階之轉移函數。最後依規格要求設計控制器，以實現具飛馳電容之多階層升壓型直流直流轉換器電路之控制。本文實作利用FPGA (Field Programmable Gate Array)硬體電路晶片實現演算法撰寫及控制器設計。實驗結果顯示此控制架構與控制器在穩態及負載切換、輸出電壓變動之暫態波形上，皆能維持穩定。

In this thesis, we construct a mathematical model and derive the transfer function for the multilevel flying capacitor converter circuit. To derive the (2+1)-level and (3+1)-level flying capacitor converter circuit as an example, we find that no matter what the order of the circuit, the transfer functions can be simplified as second order system through parameter design. Finally, according to the design specifications of the controller, we can implement the control of multilevel flying capacitor converter circuit. All the algorithms and controllers are implemented in Field Programmable Gate Array (FPGA). Experimental results show that this control architecture with the controller is able to maintain stability in the steady-state and transient load waveforms.
