style="text-indent:2em;">这是指在所有其它影响量保持不变时,由于负载的变化使输出电流在额定值I和零之间变化时所引起的输出电压的相对变化量.负载稳定度的符号为sl由定义可知第二节稳压原理是用来说明线性调整型晶体管直流稳压电源工作原理的一种基本稳压电路。El是整流滤波电路的电动势RI是整流滤波电路的等效内阻,U是未经稳定的输入电压,U2是输出的稳定电压,I是输出电流,RL是外负载,磁是过电流保护电路的检测电阻,BG为调整管,BG2为放大管,D为基准稳压管,R和R2为取样电阻.这种将调整级与负载串联的稳压电源称为串联型稳压电源。其调整作用是连续的,所以又称为线性调整型稳压电源.调整作用是利用负反馈的原理来获得的:电阻R和R2,组成的分压器用来把输出电压U的变动量的一部分取出来,加至放大管BG的基级上,所以R和R2支路称为取样电路.从R取得的电压U叫做取样电压.为了保证取样电压只反映U的变动,而不受BG基极电流1的影响,在设计中要使通过R和R2的电流I8远大?HZ。由硅稳压直流管直流稳定电源自载稳定度指的是?Df和限流电阻R组成的电路用来提供基准电压,它等于稳压管D的稳定电压Ur,加到放大管BG的发射极。BG起着将取样电压Ub和基准电压Uz进行比较并对其差值进行放大的作用,所以称为误差放大器U和Uz的差值UAB称为误差电压,UAB=UR是误差放大器的负载电阻。从BG输出的控制电流加到调整管BG的基极用来控制BG的基极电流,达到维持输出电压近似不变的调整作用?/p>以上就是关于“直流稳定电源自载稳定度指的是?”的简单介绍,我们公司还有直流稳定电源、石家庄数英仪器有限公司等诸多相关产品,如果您比较感兴趣,可以跟我们联系获取更多详细资料?/p>
