摘要
本文针对低电压大电流异步电机的过电流保护,基于霍尔检测原理,采用UGN3503LT霍尔传感器和磁环设计了一种用于低电压大电流异步电机的过电流保护。采用IR2110S元件,防止瞬间大电流击穿功率模块。系统以DSP系列中的TMS320LF2407为核心,实现了对低电压大电流异步电机及时有效并且具有良好隔离效果的过电流保护。此系统还具有稳定可靠,简单易行的特点。
This paper presents a way of over-current protection of low-voltage and high-current induction motor by using a Hall Sensor. This system uses UGN3503LT of Hall Sensor and suited magnetic loop. To prevent the breakdown of power module by instantaneous high current, the system uses IR2110.TMS320LF2407 of DSP is used as controller of the system, and the system is well-isolated and timely .It is a reliable and stable system.
