Computer-aided optimizing design of discharge circuit for a capaci-tor stored energy spot welding machine

Based on simplifying for resistance-inductance.capaci-tance discharge circuit of a capacitor stored energy spot wehting machine,discharge circuit mathematical model was set up and the discharge current curve was simulated by the aid of computer.The influence of induetance and capacitance on the shape of the discharge current curve,peak value current and time of the discharge was studied systemically,in order to guide the design of discharge circuit.
