Abstract
The electrical discharge machining process provides one of the best solutions available for machining a growing number of high-strength and corrosion -and-wear resistant materials. It operates on the principle of erosion of metal surfaces by an interrupted electric spark. The power supply design and configuration requirements for producing the desired spark have always been a challenge to the researchers. This paper presents an example of a configuration of a power supply used for the EDM process. The power supply (a pulse power generator) is based on an electronic current source utilising MOSFET transistors. This article describes both simulation tests carried out on the circuit, and results of laboratory tests.
