因此为了得到输出电压误差,反馈电阻的取值应该很大。由于3V工作电压时,MAX4544的导通电阻仅为120Ω,因此开关MAX4544引入的误差电压很小,即使低输出电压也是如此。当使能升压变换器,且其输出电压超过MAX810的复位门槛电平并经过复位延迟后,MAX810的输出将由高变低,使Q1导通,连通负载。同时,MAX810输出的低电平使MAX4544的COM端与NC端(常闭端)接通,使得反馈电阻由Q1的源极切换至Q1的漏极,从而允许从远离变换器的负载端对输出电压进行调节。上述MAX4544的开关过程也把MAX810的输入端从Q1的源极切换到Q1的漏极,这样一来,MAX810可以用来监测负载是否过载。

高压高压熔丝在高压电塔与电线杆上,经常使用兼具启断开关功能的熔丝链开关(FuseCutout),作为输配电系统的过电流或短路保护。其他类型编辑可恢复式丝自恢复丝或过流保护片[3]。自恢复丝自恢复丝温度片温度片当温度超过一定的温度后会变形导致断电,温度回复即可复原。温度丝温度丝(Thermalcutoff)常见于现今的电热类装置之中,当温度超过一定的温度后会熔断。具有温度丝的装置例如:电锅、电热器、咖啡机、吹风机等。温度丝的规格中虽也有容许电流一项,但要注意的是:温度丝并没有与电流丝一样的电流保护作用,不可混淆。

高压软启动器必须有一个高性能的控制核心,能对信号进行及时和快速地处理。因此这个控制核心一般采用高性能的DSP芯片,而不是低压软启动器的普通单片机芯。低压软启动器主回路由三组反并联的晶闸管组成。而在高压软启动器中,由于单只高压晶闸管的耐压能力不够,所以必须由多个高压晶闸管串联进行分压。但是每个晶闸管的性能参数没有完全一致。晶闸管参数的不一致,会导致晶闸管开通时间不一致,从而导致晶闸管的损坏。因此在晶闸管的选配上,必须保证每一相的晶闸管参数尽可能地一致,并且每一相晶闸管的RC滤波电路的元件参数尽可能一致。高压软起动器的工作环境容易受到各种电磁干扰,因此触发信号的传递必须可靠。高压软起动器中。

而且还具有比硅整流元件(俗称"死硅")更为可贵的可控性。它只有导通和关断两种状态。可控硅能以毫安级电流控制大功率的机电设备,如果超过此功率,因元件开关损耗显著增加,允许通过的平均电流相降低,此时,标称电流应降级使用。可控硅的优点很多,例如:以小功率控制大功率,功率放大倍数高达几十万倍;反应极快,在微秒级内开通、关断;无触点运行,无火花、无噪音;效率高,成本低等等。可控硅的弱点:静态及动态的过载能力较差;容易受干扰而误导通。可控硅从外形上分类主要有:螺栓形、平板形和平底形。可控硅元件的结构不管可控硅的外形如何,它们的管芯都是由P型硅和N型硅组成的四层P1N1P2N2结构。见图1。它有三个PN结(JJJ3)。
