甲類分立元件功率放大器電路圖15W

此功率放大器電路是使用雙20V電壓電源,提供15W的不失真功率在8歐姆負載的時候。Q1 經營在共同的放射器, 輸入信號通過對偏壓管子包括Q8, Q9 、D6 、D13 和D14 。Q8 和Q9 提供恒流偏壓, 產品階段減到最小由分離darlington 對(Q2,q4) 形成并且(Q7, q11) 。前二支晶體管是力量Transitors, 具體地2N3055 和MJ2955 。7.02K 電阻器, R16 被做了使用4.7K 、680 歐姆, 和二820 歐姆的系列組合。1.1K 電阻器, R3 被做了使用一100 歐姆和1K 電阻器。沒什么問題吧,好理解吧.

This amplifier uses a dual 20 Volt power supply and delivers 15 watts RMS into an 8 ohm load. Q1 operates in common emitter, the input signal being passed to the bias chain consisting of Q8, Q9, D6, D13 and D14. Q8 and Q9 provide a constant current through the bias chain to minimize distortion, the output stage formed by a discrete darlington pair (Q2,Q4) and (Q7,Q11). The last two transistors are power Transitors, specifically the 2N3055 and MJ2955. The 7.02K resistor, R16 was made using a series combination of a 4.7K, 680 Ohms, and two 820 Ohms. The 1.1K resistor, R3 was made using a 100 Ohms and a 1K resistor. You can use this circuit with any walkman or CD player since it is designed to take a standard 500mv RMS signal.are you understand.
