Improving Electrical Efficiency of Edm Power Supply

Emanoil Toma / Carmen Mihaela Simion
Published Online: 2014-12-30 | DOI: https://doi.org/10.2478/aucts-2014-0016


This paper briefly presents the principal types of Pulse Generators for Electrical Discharge Machining and ways to improve electrical efficiency. A resonant converter with series-parallel LCC circuit, for EDM applications, was analyzed by PSpice simulation. The performances of EDM Power Supply were improved by adding an energy recovering - voltage limiter circuit. The shape of current pulse was changed by adding a supplementary MOSFET Switch in parallel with the gap. Two or more converters can be parallelized, in this way output current can be changed. A bloc-schema was conceived for EDM experimental set up
