|Abstract:||The process energy source is the main unit of the electrotechnical system for the spark erosion. The different fields of EDM application have made it necessary to develop different types of energy sources. In this paper, a brief review of the main types of energy sources is presented and the specific uses that are supposed to deal with. The examples are needle pulse energy sources with very short pulse duration (< 500 ns) and series-parallel resonant converters. The short needle pulse source does not produce any thermal-affected zone at the workpiece so that refinishing is not necessary. The series-parallel resonant converter can be forced in the robotics technology, which is of special interest for operations in critical rooms or environment|
