Abstract
The design of the LLC resonant converter is presented for use in Electric discharge machining (EDM) applications. The converter is designed to operate with a 3phase ac input voltage and will output controlled dc voltages during thestriking and arc conditions of EDM process. The method of the LLC resonant converter can operate at zero voltage and zero current transitions, we change the output current and control the current waveform of the EDM.
