| As an important part of EDM (Electrical Discharge Machining) machine, pulse generator isoneofthemainfactorswhichinfluenceEDMprocess.The characteristic of pulse generator of EDM has been analyzed , basing on the reading totherelatedChinese andforeignliterature.Aimingat thelowefficiencyofthepulsegeneratorforthe EDM machine, a new type of pulse generator for EDM is designed. The half bridge DC/DCconverter is used in the main circuit of this generator, and the resistances and the workingfrequency transformer is replaced. Designed the 60A peak current high and low voltagecombined-structureEDMpulsegenerator.In this thesis , the topology , principle, control scheme of EDM pulse generator has beendiscussed in detail. The main circuit, control and protection circuit, timer circuit has beendesigned in detail. The select of electron parts has been introduced in detail. 60A peak currenthigh and low voltage combined-structure EDM pulse generator has been developed, and thefeasibilityofsystemhasbeenconfirmedbytheexperiment.
