replaces phase trigger to eliminate harmonic wave pollution on electric power grid. Once Ui(k) is calculated, on-off ratio of electric current is calculated to control the heaters by PWM. Consequently... application in three-phase electrode adjusting system of submerged arc furnace [J]. Journal of Central South University Technology, 2013, 20(2): 405-412.
