摘要
该文建立了半桥式逆变电源及其连接的配电网的完整的非线性的Matlab仿真模型。仿真试验分析了弧焊逆变电源工作过程及其动态特性 ,接于配电网的邻近用户的电压、电流及其THD(总谐波歧变率 ) ,弧焊逆变电源输入电压、电流的THD及频谱分析。
Nonlinear Matlab simulation model of half-bridge inverter and it's connected power distribution network was setup. The working process , dynamic character ,input voltage ,input current and their THD of welding inverter were analysed through simulation, so as to current ,voltage and their THD and spectrum of neighbor User . Dynamic response of representative electrical quantities when short circuit occurred caused by dropping of melded welding rod were shown in curves.
