摘要

本論文探討的「三相交流直流整流器」，提出了新的三相橋式開關的數位控制方法，使用閉迴路的方式產生穩定的輸出直流電壓值，三相交流直流整流器比單相交流直流整流器，有比較小的直流輸出漣波電壓，一般的三相交流直流整流器的整流元件是使用二極體，實際上二極體有0.7 伏特的導通電壓，在低電源管理的應用上二極體有較低的效能，因此，使用功率電晶體(power MOSFET)能夠降低導通電壓，使轉換器能改善上面這個問題，數位邏輯控制的優點是在於有快速的響應時間、控制簡單，而交流的訊號來源是由直流馬達與發電機產生，一般轉換器可適當的用於電源管理方面，例如：低壓的穩壓器、直流-直流轉換器等，轉換器是使用台灣積體電路公司零點三五微米兩層多晶矽四層金屬互補式氧化物半導體5 伏特的製程，轉換器含PAD 晶片面積為1.957mm*1.627mm。

Design and implementation of the three-phase AC-DC rectifier is presented in this thesis. Proposing a new digital control theorem of bridge switch uses close loop
circuit to provide stable DC output voltage. The DC output ripple voltage of the three-phase AC-DC rectifier is lower than the single-phase one. In general,rectification components of three-phase AC-DC rectifiers use diodes. In fact,the threshold voltage of the diode is 0.7V. The efficiency of diode rectifier is low for low power management application. Therefore, the power MOSFET has less threshold voltage, and the proposed converter can improve the above problem. The advantages of the digital logic control method are fast transient response and simple control. AC sources are generated by the DC motor and the generator. In general, the proposed converter is suitable for the power management applications, such as the low dropout regulator and the DC-DC converter, etc. The three-phase AC-DC rectifier has been implemented with TSMC 0.35μm CMOS 2P4M technology for 5V power supply. The
chip area of the proposed converter is 1.957mm*1.627mm with PADs.
