基于GAL的焊接电源时序电路设计

The Logic Design of Sequence Circuit of Welding Supply Based on GAL

文章介绍了焊机电源采用通用阵列逻辑GAL(Generic Array Logic)芯片进行的电路功能设计、硬件设计及GAL16V8芯片的工作原理及程序设计。GAL是Littice公司研制的一种可电改写、可重编程的低密度PLD器件,取代了传统的通用数字电路,提高了时序设计的灵活性。

This paper introduces the power supply of welding machine uses GAL（Generic Array Logic） wick in electrical function design, hardware design, the principle of GAL16V8 wick and programming are introduced. GAL is a kind of electrically adaptable and repeated programming low density PLD device by Lattice company, which replaces the traditional general digital circuit and improves the flexibility of sequential design.
