摘 要

應用感應加熱的技術已可達到系統上的高效率、高品質與低污染之特性，並且加熱處理技術已在相關領域中佔有一席重要之地位，尤其應用在金屬表面快速加熱部份。

本篇論文對於印刷電路板的壓黏設計中較重要的加熱物件性，於實驗中分析說明，並且使用變頻技術達到印刷電路板壓黏所需要的恆溫的條件。實驗架構為電壓饋入式全橋式電源轉換裝置，應用於負載串聯共振式感應加熱系統之上，功率開關具備零電壓切換的性能，具降低功率開關切換應力、切換損失及改善電磁干擾現象等特點，成功達到提高加熱效率之目的。

最後，本研究將對感應加熱系統其操作特性與整體效率進行說明與量測，同時對於加熱物件的加熱效果做一探討。

Abstract

Using induction heating could reach a high efficiency, high quality, and low pollution system. The heating technique is important in related fields, especially in the rapid heating on the surface of metals.

This paper describes the important characteristics of heated objects in a printed circuit board bonding design first, then uses variable- frequency technique to achieve constant temperature in the bording process. A load series resonant induction heating system with voltage source full bridge inverter has been constructed and tested. The system can reach reducing switching losses, component stress, and electromagnetic interference of power semiconductor devices, and therefore reaches high heating efficiency.

Finally, the control characteristics and whole system efficiency were measured and analyzed.
Keywords：full bridge inverter、variable- frequency technique.
