| Abstract |
In this paper, the authors present the structure of a new converter for DC arc furnace. This converter uses diode rectifiers associated with choppers to control the arc current. A constant power control is used on the chopper. With this special control, the flicker effect on the power network is very low and the productivity of the furnace can be increased. To evaluate the gain on flicker and furnace productivity, simulations are done with Matlab Software. These simulations take into account arc voltage measurements on a 100 MW DC arc furnace supplied by thyristors rectifiers. |
