摘要

本論文主要實現一具有電源監控功能的LLC諧振控制器。此諧振控制器內建電壓控制頻率電路作脈波頻率調變，同時內建電壓監控電路作異常電壓的保護。
首先分析諧振轉換器工作，以SPICE模擬分析LLC諧振半橋轉換器電路，實現具有電源監控功能的LLC諧振控制器，將設計階段模擬波形和實際控制器波形作確認，最後在電源系統作晶片測試，驗證晶片設計和實測的一致性。

This thesis focuses on the study and design of a LLC resonant controller built-in supervisor function. This resonant controller is designed with voltage control frequency circuit to implement the pulse frequency modulation function and also built-in the voltage supervisor function for the abnormal protection.
Firstly, study the principle of resonant converter and discusses the SPICE simulation result of LLC resonant half-bridge converter. Secondly, Design and realize the LLC resonant controller. Examine the controller’s data between the design simulation and real chip test. Finally, examine the consistency in performance between design and actual measurement at power system.
