Abstract :
Machining micro-pits on hip implant for lubrication purpose is the most effective way to minimize wear as well as prolong the lifespan of the hip implant. Several works on designing Pulse Power Generator for machining micro-pits has been conducted but suffer from micro crack. Thus, in this research, a new design of Electrical Discharge Machining Pulse Power Generator is implemented which consist of Flyback converter circuit and Current Mode Controller Integrated Circuit. The work involves the design and development of the SIMULINK behavior model of the overall system. The machining performance of the system is evaluated by changing the input voltage.
