An initial design for a power circuit of a new plasma system is proposed and implemented in MatLab code. The plasma device is a torus and requires an excitement of wires, which are wrapped around the torus for a toroidal field and a poloidal field coil placed at the outer part of the device. This poloidal coil structure ignites an electrical field inside the chamber and that yields to a circular magnetic field inside the plasma. The proposed electrical design for this poloidal field equipment has some components including the alternating current unit and the direct current one. The circuit first uses an ac-dc converter, in order to transfer the ac grid to the dc one. Then it uses a switching scheme and a discharge circuit. The operation voltages for the poloidal field are estimated to be 1 kV, respectively. It has been proven that the designed system can produce an almost dc current with 66 V fluctuation, which is under the limit of 6%, considering the high voltage of 1kV.
