analog control circuit

基本解釋

At first we established an AC small-signal model of welding inverter and designed a digital controller on the basis of analyzing a typic analog welding control circuit.
本文在這部分的研究工作中，首先建立了弧銲逆變電源的交流小信號(hào)模型，竝對(duì)典型的模擬控制電路進(jìn)行了分析。
In traditional method which uses analog control circuit, some disadvantages such as difficult debugging and aging component, are unavoidable. Digital control method is not mature now.
目前感應(yīng)加熱裝置多採用模擬控制電路，模擬電路不可避免的存在調(diào)試睏難、元件易老化等缺點(diǎn)，感應(yīng)加熱電源的數(shù)字控制技術(shù)發(fā)展尚不成熟。
The analog circuit consists of power-supply modular, signal pickup circuit, analog filter amplifier, gain control circuit, power ground lifting circuit and signal limit circuit of A/D channel.
