Research On Current Source LCC Resonant Converter For An EDM Power Supply

The Electrical Discharge Machining (EDM) has been a very important method of machining, and performs its alternative function in industry. The performance of EDM power supply will be the main infection to the arts and crafts of EDM.At present, the key technology of EDM power supply is how to design a power supply with simple circuit, finish maching, high heat availability, high efficiency and wasting less energy, So a current source LCC resonant converter is selected for the EDM power supply in this paper, the prototype of current source and load adaptability are used to get the performance of simple circuit, finish maching, high efficiency and wasting less energy.At first, the status quo of EDM power supply is introduced in this paper, The design of an EDM power supply is comfirmed after the characteristics of current EDM power sypply has been summarized. Secondly, the principles of the LCC resonant converter are analyzed in detail. A good method of parameters design is selected, and parameters of converter are optimized after the infections of the parameters to EDM power supply be analyzed and simulated. Thirdly, the feasibility of the EDM power supply is ensured through modeling and simulated. At last, a 20A peak current prototype has been designed as an EDM power supply by LCC resonant converter. The correctness of the designing method on an EDM power supply with current source LCC resonant converter has been verified by experiment. So the LCC resonant converter act as EDM power supply feasibily...
