因應電力需求量和穩定度要求，本研究研製高功率不斷電系統與開關模組驅動電路，不斷電系統採用三相四線半橋式轉換器作為高功率的傳輸媒介，並將微控制器Renesas RX62T作為控制核心。
在交流穩壓模式下，轉換器採用分切合整數位控制法，並結合正弦脈波寬度調變以實現回授控制。與傳統類比控制法相比，分切合整數位控制法將系統參數變化，如直流鏈電壓、交流輸出電壓、電感值和切換週期等皆納入考量，抵消參數變化對於受控體的影響，並直接計算出開關責任比率。
本研究在控制法中加入負載電流估測法。每一切換週期內預測負載端的濾波電容電流與負載電流變化量，使轉換器能夠輸出穩定的三相弦波電壓。為了測試高功率不斷電系統，提出硬體在環測試。此測試法的直流鏈端由電源供應器負責穩壓，電路架構上使兩部轉換器具有共同的直流鏈及交流端，最終使功率於兩部轉換器內進行循環。本研究針對高功率開關模組設計驅動電路，內容將詳細介紹如何根據數據表設計驅動電路參數、選擇驅動電路架構以及保護電路等實務考量。
本研究主要貢獻包含：(1)採用分切合整數位控制法，簡化繁瑣計算過程並將電感值衰減納入考量。(2)結合負載電流估測法，於每一切換週期內，即時地預測下一切換週期欲補償的電感電流變化量，透過分切合整數位控制，輸出穩定弦波電壓。(3)提出硬體在環測試法，利用轉換器抽取各式負載。使高功率不斷電系統之交流穩壓功能得到驗證。(4)設計高功率開關模組驅動電路，穩定且高效率地使轉換器進行功率轉換。

In response to the demand for power and stability, this research develops design and implementation of high-power uninterruptible power systems and IGBT module drivers. The uninterruptible power systems use three-phase four-wire half-bridge converter as high-power transmission medium and the microcontroller Renesas RX62T is the control center of the systems.
In the ac voltage regulation mode, the converter adopts the division-summation (D-Σ) digital control, combined with sinusoidal pulse width modulation (SPWM) to realize the feedback control. Compared with the analog control, the D-Σ digital control takes into account the system parameter variations, such as dc link voltage, ac output voltage, inductance value, and switching period, to offset the influence of parameter changing on the controlled plant, and calculates the duty ratio directly.
In this research, the load current estimation is also applied to the D-Σ digital control. In the load current estimation, the filter capacitor current variations and load current variations can be predicted in each switching period, so that the converter can output stable three-phase sinusoidal voltages. In order to test the high-power uninterruptible power system, “Hardware in the Loop” is proposed. The dc-bus is regulated by the power supply. The circuit structure makes the two converters have a common dc link and ac terminal. Finally, the power is circulated in the two converters.
This research also designs drivers for the high-power IGBT module used in the converter. Describe in detail how to design the parameters of the drivers, select the architecture of the drivers, and design the protection circuits based on data sheets.
The main contributions of this research include: (1) Using D-Σ digital control to simplify the cumbersome calculation process and take into account the attenuation of the inductance. (2) Combined with the load current estimation, the inductor current variation compensating in the next the switching cycle is calculated instantaneously, and output the stable sinusoidal voltages through D-Σ digital control. (3) “ Hardware in the Loop” is proposed, and various loads are extracted by using converter. The ac voltage regulation function of the high-power uninterruptible power system is verified. (4) Design high-power IGBT module drivers to make converter convert power stably and efficiently.
