逆变式电焊机用电流传感器的设计

Design Of Current Sensor Used for Contravariant Welding Machine

针对逆变式电焊机的特点,设计了能满足其需求的霍尔电流传感器,该传感器具有抗干扰能力强,在外界环境恶劣条件下性能稳定等特点。介绍了该传感器的工作原理、设计理念及具体的设计过程。

In view of the characteristic of contravariant welding machine,designed a kind of Hall current sensor to meet its need,this sensor had strong ability of anti-jamming,and can work steadily under the scurviness condition also. Introduced the working principle and the design idea of the sensor, then made the introduction to the concrete design process.
