MEI Jian, DENG Zhiliang (Dept. of Electronics and Information, East China Shipbuilding Institute, Zhenjiang Jiangsu 212003,China)
Introduces a new design device of hardware system and software system against electric shock based on a new kind of MCU. Hardware consists of control circuit based on PIC series MCU and power circuit based thyristors. And software is designed according to PID control algorithm. Thus this device can not only protect people from electric shock, but also control the welding current in order to gain better welding effect.
