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模型，竝對典型的模擬控制電路進行了分析。
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，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.
