“…In EDM, Simple RC power generators or transistor generators with a resistor acting as a current limiter are made to make sure that gap current only goes up to the maximum value. Sometimes, the design of the direct current power source itself may also cause voltage variations at the transistor keys output [28]. From the reported results, it has been seen that the required machining outputs determine the kind of generator choice in EDM.…”

The electrical discharge machine (EDM) is an unconventional machine process. It uses thermoelectric energy to erode the work material. Usually, the EDM is employed to machine the hard to cut materials. The extraordinary characteristics of the EDM make the process more versatile for advanced manufacturing. The process is used to attend the intricate geometry with a high degree of accuracy. In the present scenario the manufacturing industries are meeting new challenges at frequent intervals due to the market competition and unique attributes of the materials. Ever changing customer requirement forces the continuous improvement in the machining technology, especially in unconventional machining processes like EDM. The present work reviews the progress of the key technology of the EDM which mainly affects output of the process. The reported work supplies the rigorous analysis of the major elements of the EDM in phase manner which includes the Power generation, control Units and servomechanism. In each section the concern issues are highlighted and reported proper remedies. In nutshell the EDM development from the start to the present stage is reported.

“…These types of pulse generators are particularly suitable for micro‐EDM. Mysinski [53] has used TOP‐switch‐based VS and CS, along with an interfacing circuit composed of an H‐bridge to construct a low power (35 V, 3 A) EPG. Wang et al [54] have used a very high‐frequency resonant pulse generator for micromachining on the mesoscopic scale.…”

This article presents a model of pulses in Electrical Discharge Machining (EDM) system. There are several mathematical models have been successfully developed based on the initial, ignition and discharge phase of current and voltage gap. According to these models, the circuit schematic of transistor pulse power generator has been designed using electrical model in Matlab Simulink software to identify the profile of voltage and current during machining process. Then, the simulation results are compared with experimental results.
