isolation amplifier
ge!{fongd。卿隔离放大器(isolationamplifier)能绝缘隔离信号与测量电路之间高电位的一种弱信号放大电路。其原理框图如图所示。Ui为传感器的输出信号，接到前置放大器N的同相输人端与输人信号“地”之间。输人信号“地”与输出信号u。的“地”之间有时存在着较高的电位差，例如可达千伏级。Ui经前置放大器放大后，再经调制器、变压器Tl和解调器后输出。所以变压器Tl负担信号的传输和电位隔离。但是，前置放大器N和调制器都需要一定功率的电源，这个电源(直流)是从+15V电源侧经过振荡一器、变压器TZ和整流滤波后获得的，所以TZ负担电功率的传输和电位隔离。TZ和Tl上边的箭头指向分别代表功率流向和信号流向。通常在隔离放大器后，接测量放大器。┌────┐ │ 卜C。 │ │ N+ │ │十 │ └────┘ ┌─┐ │ │ ┌────┐┌┴─┴┐ │整流滤波││振荡器│ └────┘└───┘隔离放大器原理框图
