Micro-EDM is a promising noncontact micro machining process; where the precisely controlled electric spark occurred between the tiny electrodes and erodes the material from electrically conductive work piece. Application of this Micro EDM is rapidly growing in manufacturing of metal products irrespective of its hardness having geometric features in range of micrometer to nanometer scale. In order to ensure the material removal in the order of few cubic micrometers it is desirable to use a low energy, shorter pulsed discharges at very high frequency. In this study, the detailed literature review related to low energy and short pulsed power circuits to use in Micro-EDM process conditions has been carried out. The advantages and issues of obtaining such high frequency short pulsed low energy discharge have been critically studied to set the future directions for further investigation.
