中文摘要 | 國家實驗研究院儀器科技研究中心(以下簡稱儀科中心)開發一套半導體致冷系統,其特點為低成本及易整合於量測儀器上。半導體致冷系統包括熱電阻式溫度量測、脈衝寬度調變式電流控制與溫度資訊顯示。溫度量測解析度可達0.1℃,電流控制輸出最高可達2 A,並設計具有自動溫度回饋調整電流機制。本文詳細介紹相關電路設計與量測情形,以提供國內相關領域之應用。 |
英文摘要 | We report the design of TE cooling control system with a cost effective, general purpose, and easily to integrate with other measurement system. The TE cooling control system consists of thermistor type temperature measurement circuits, current output control circuit based on PWM, and data display. The temperature resolution of our measurement system is 0.1℃. Maximum output current can reach to 2 A. The temperature measurement and current output of the automatic feedback control system are achieved by the implementation of an analog and digital background balancing circuit. The article also introduces the system structure, design, and measurement results that it looks forward to providing those information for any applications in related industries. |
