| Abstract: | 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. |
