Abstract

According to the processing needs of pulse power supply for the micro hole machining, a multi-mode pulse power supply including RC mode, controlled resistance mode, controlled capacitor mode, and other several power supply modes is developed for the micro-EDM system, whose CPU circuit is based on a microprocessor and two complex programmable logic devices (CPLD). In micro-EDM, the micro-energy pulse power not only realizes nanosecond grade electrical pulse signal, but also can achieve a wide range of optional in energy with the control of power transistors and electrical relays which can choose the electrical processing mode, open circuit voltage, resistance, capacitance, pulse-on time, pulse-off time and so on. Finally, 2×128 array holes with deviation of 2μm in diameter can be stably realized with the multi-mode pulse power supply.
