摘要

本論文係提出一新穎之高升壓轉換器。藉由不同的脈波調變控制策略及改變二極體陽極的連接位置，可以得到三種不同的電壓轉換比。這些轉換器主要是由靴帶電容及升壓電感所建構而成。最重要的是，當兩個不同的升壓電感串聯時，轉換器仍可正常工作。除此之外，雖然轉換器有三個開關，但只須一個半橋閘極驅動器及一個共地閘極驅動器來驅動此三個開關，不需要任何隔離閘極驅動器。於本論文中，將詳細敘述所提之高升壓轉換器之基本操作原理及其相關之理論分析與推導，最後搭配實作結果來驗證每一所提轉換器之有效性。

In this dissertation, novel high step-up converters are presented. By using different pulse-width-modulation (PWM) control strategies and by changing the connection position of the anode of the diode, three different voltage conversion ratios can be obtained. These converters are constructed mainly based on bootstrap capacitors and boost inductors. Above all, two boost inductors with different values, connected in series, can still make the proposed converters work appropriately. Furthermore, although there are three switches in each converter, only one half-bridge gate driver and one low-side gate driver are needed, but no isolated gate driver would be needed. After the basic operating principles and mathematical deductions of the proposed converters are described, some experimental results are provided to verify the effectiveness of these converters.
