Software Design of Pulse Generator Based on Single-Chip Computer and CPLD


Article Preview

The purpose of this article is to study and devise pulse signal source of electrical discharge machining(EDM). The technology of EDM is the necessary key technology in various processing methods. Electrical discharge machining pulse power aims to convert the industrial frequency alternating current into certain frequencies pulse current to supply energy for electrode discharging to removal metal. Pulse power generator, controlled by an embedded MCU, can produce high voltage or low voltage discharge pulse waveform. After the research on characteristics and principles of many pulse powers, a novel, intelligent, high frequency pulse power supply with adjustable amplitude, frequency and duty is developed which has a favorable foreground in engineering application and a great theoretical significance. This paper is to realize the design of EDM pulse signal source based on the method of combining single-chip computer and complex programmable logic devices (CPLD), to satisfy the technical requirement of periodic variable and machining efficiency improving.
