The high frequency switch-mode power supply focused by this subject mainly used in galvanoplastics(NDF), electrification(NCF), electrical chemistry(NHF), and excitation(NLF).
The micro-EDM prototype was composed of three dimensional stage,transistor type isopulse generator with pulse duration of 80ns,and environmental maintaining system.
Moreover, the proposed control system is of some fault diagnosis and protection functions, such as overcurrent, overvoltage-undervoltage, overtemperature and parameter overrun.
