This paper describes development of the electric current pulse supply unit. This system is used to improve the problems of non-uniformed solidification structure, which is made in melting process of light weight alloy. The power supply switch of our system use MOSFET switch and gate control use PWM signal. We have simulated the designed circuit and made to PCB for the current pulse supply unit. The power circuits are simulated by a PSIM software. In the experiments, we have confirmed that the experiment results are follow the simulation results very well.
