|摘要:||In recent years, energy harvesting systems have been receiving much more attention. Energy harvesting systems are used to harvest energy from the environment, such as solar, thermal and vibration energy, and convert them into electrical energy. Then, the harvesting electrical energy can be stored in the batteries and be used as a voltage supply of the loading circuit.
This thesis introduces a design of a high-performance rectifier with active-controlled switches. By taking the advantages that turn the switch on lately and turn the switch off early of the unbalanced-biased comparators with the offset voltage, the reverse leakage current caused by the gate charging delay of the MOS transistor, which can't allow the MOS transistor to respond instantly, will be minimized. Besides, the comparator will actively detect the drain and source of the MOS transistor. When the voltage of the input side is higher than the voltage of the output side, the rectified loop generates, and the capacitance of the output side is charged.
This circuit is implanted with TSMC 0.18μm 1P6M 1.8/3.3V CMOS process. When the amplitude of the AC voltage is 3V, the input frequency is 200Hz, the loading capacitance is 10μF, and the loading resistance is 35kΩ, the rectifier has the maximum power conversion efficiency of 93.39% and the voltage conversion ratio is 97.12%. Furthermore, the power conversion efficiency is 90.11% and the output voltage of the rectifier is 2.9541V with the loading resistance of 95kΩ, which means the voltage conversion ratio is 98.47%.|
近年來能源擷取系統越來越受到重視。能源擷取系統被用來擷取環境能源，例如太陽能、熱能、振動能等，並將這些能源經過轉換器轉換為電能。獲得的電能可以儲存在電池中，供給負載電路使用。 本論文介紹一個具主動控制開關的高效能整流器設計。利用擁有偏移電壓的非平衡比較器，其較晚導通與提早關閉的特性，減少因為功率電晶體閘極電容充放電延遲，而導致電晶體無法瞬間關閉，造成逆向漏電流的情形。除此之外，比較器能主動偵測功率電晶體的源極與汲極，當輸入端電壓大於輸出端電壓，才會形成整流迴路，對輸出端電容充電。 本電路採用台積電TSMC 0.18μm 1P6M 1.8/3.3V CMOS製程實現電路。當輸入交流電壓振幅為3V、輸入頻率200Hz、負載電容為10μF及負載電阻為35kΩ的狀況下，擁有最高的能源轉換效率93.39%、電壓轉換比例97.12%。而整流器在負載電阻為95kΩ時，能源轉換效率為90.11%、整流器的輸出端可以獲得2.95V的電壓，即電壓轉換比例可達98.47%。
