用霍尔元件实现功率测量的新方法研究

Study of new power measurement method using Hall component

在分析现有的功率测量方法的基础上,提出了一种用霍尔元件实现功率测量的新方法—霍尔元件法。通过一个合适的测量电路,把功率转化成霍尔元件的磁通量和控制电流的乘积,然后,根据霍尔元件输出电压的大小,便可以计算出功率值。实验结果表明:测量准确度优于±0.1%。

Based on the comprehensive reading the references of the power measurement, a new power measurement method-Hall component method, which based on the Hall effect, is presented. By use of a proper measurement circuit,the power is translated into the product of flux and control current. According to the output voltage value of Hall component , the power value can be figured out. The experiment results show that the measurement precision is superior to ± 0.1%.
