| Abstract: | Under the theory foundation built up tecently of RLCU-type capacitor disch-arge with nonzero-current and nonzero-voltage initial condition, every typical operatingstate and its corresponding excited magnetic level are analyzed. In the concrete, reasona-ble design state is determined. By the T-type equivalent circuit in design state, and so-lving its corresponding circuit equations, the varying rules of related electric and inagne-tie variates are gotten, the basie formulas for aeeurate and reasonable engineering designare Provided, and favour condition for developing and iniproving thyristor arc weldinginverter is Produced. |
