固态继电器控制交流电机软起动

A Soft Starter for AC Motor Controlled by Solid state Relay

介绍用ＮＥ５５５控制固态继电器实现交流电机软起动，以及电流闭环控制的设计。实验证明，该方案具有良好的软起动性能且造价低。

This paper introduces the soft starter for AC motors based on solid state relay (SSR) controlled by NE555 and the design of the current close loop.The practice proves this strategy has good performance and low cost.
