Making a Regulated 9V Battery Eliminator Circuit

该职位提出了一个受管制的9V电池消除器电路，由史蒂文Chiverton先生，这是本博客的狂热读者和经验丰富的电子爱好者的Avid Reader先生构建和调查。让我们从他那里了解更多。

9伏电池消除器电路测试：

Circuits built 2x each circuit ive made a small modification to it buy adding a low esr 1000uf filetr capacitor between each circuits positive and negative output, latter after construction i decided to test them both but i removed the filer capacitor to note the difference between each 9 volts battery eliminator circuit.

第一次测试与电池消除器带有1000UF低ESR滤波电容，我喂入12伏直流，输出为A9.21伏特DC。然后测试了没有低ESR滤波器电容的电池消除器，我喂它相同的12伏直流，输出少于9.05伏特DC。

测试2，我将变压器的电压输出变为9伏直流，因此我将9伏直流进入电池消除器，用1000UF低ESR滤波电容，其输出为8.18伏特DC。然后我将相同的9伏特DC进入电池消除器，没有1000UF低ESR滤波电容，其输出为7.67伏特DC。

Test 3 , then i changed the transformer output voltage to 7.5 volts dc and so i fed that into the battery eliminator with the 1000 low esr capacitor and its output was ,6.75 volts dc. Then i fed the same 7.5 volts dc into the battery eliminator without the 1000 low esr filter capacitor and the output was then 6.2 volts dc .

试验4，我将变压器电压输出更换为6伏直流，然后用1000UF低ESR滤波电容器馈入电池消除器，其电压输出为5.30伏特DC。然后我将相同的电压送入电池消除器中，没有1000UF低ESR滤波器电容，其输出为4.88伏特DC。

测试5，我将变压器的输出电压改为4.5伏特，然后用1000UF低ESR滤波器电容器馈入电池消除器，然后输出为3.92伏直流，然后我将相同的电压送入电池消除器中的相同电压如果没有1000UF低ESR电容，则其输出为3.62伏特DC。

Last test test 6, i then lowered the transformer output to the last setting on 3 volts dc and fed that into the battery eliminator with the 1000uf low esr filter capacitor and its output voltage was then 2.44 volts dc . So then i fed the same 3 volts dc into the battery eliminator without the 1000uf low esr filter capacitor and its output voltage was then 2.29 volts dc .

Conclusion:

因此，我的研究告诉我，1000UF低ESR滤波器电容器或任何1000UF电解电容器剂量对不使用1000UF电解电容器相比提供更好的电压输出和过滤的差异。
