电流负反馈 [diàn liú fù fǎn kuì]
current negative feedback
- 摘要本文通过对电流负反馈和电压负反馈两种电路与电动式扬声器构成的系统进行对比分析，并进行实时分析测试，证实了电流负反馈对电动式扬声器失真能从实质上得到改善，从而使频响曲线更加平滑，音响系统的性能明显提高。
By analyzing and RAT testing on the current negative feedback, the voltage negative feedback and the electricity-powered loudspeaker, this paper shows that the current negative feedback can decrease the distortion of the loudspeaker, makes the frequency -response plot more smooth and improves the audio quality greatly. - 实验结果表明，系统结构完善，采用过流信号的双重保护和电流截止负反馈等措施后，使系统运行稳定，可靠性提高。
Experimental data shows us that the system has a perfect structure, because it adopts some means such as the dual protection of the over current signal and current cut-off feedback circuit, so the system has a good stability and reliability. - 分析了各部分的电路结构及特点，讨论了PWM脉宽调制信号生成、逻辑信号综合、驱动控制及电流截止负反馈的具体应用，在此基础上给出了实验数据及结果分析。
It analyses some main circuits's features, including PWM signals, logic synthesis, driver and negative feedback of current cut-off and at last gives the result of experiment.
