【正文】 he high fidelity audio course design of discrete ponent circuit method is used to design an OCL audio power amplifier. Design of power amplifier circuit consists of three parts: the input stage, promote the level and output stage is posed of two triode differential amplifier circuit, driver stage consists of a transistor, the output level consists of two triode output pipe respectively by the positive and negative two sets of power supply, the speaker directly connect between the output pipe output terminal and ground, power amplification circuit type many, now widely used in electronic circuit b class (or class ab) plementary symmetry power amplifier circuit, so here only to b class (or class ab) plementary power amplification circuit is analyzed. Key words: the OCL power amplifier, dual power supply, discrete element method, the plementary power amplification circuit 4 目 錄 引言 ..................................................... 5 1 OCL 功率放大器設計方案 ................................. 6 OCL 功率放大器設計的參數(shù)及要求 ...................... 6 OCL 功率放大器設計思路 .............................. 6 總體設計方案框圖 ................................... 6 2 電路主要器件選擇及其參數(shù) ............................... 7 2N5551 介紹 ......................................... 7 2N5401 介紹 ......................................... 7 TIP41 介紹 .......................................... 8 3 OCL 功率放大器電路設計與分析 ........................... 9 整體電路圖設計 ..................................... 9 各級電路分析 ....................................... 9 輸入級電路分析 ................................. 9 推動級電路分析 ................................. 9 輸出級電路分析 ................................ 10 4 電路板的制作及調(diào)試 ................................... 11 PCB 的印制與電路板的制作 ........................... 11 電路板的調(diào)試 ..................................... 12 調(diào)試過程中使用到的儀器 ......................... 12 電路板的調(diào)試過程 ............................... 12 調(diào)試參數(shù)的記錄與分析 ........................... 12 5 總結 ......
