| 摘 要： | 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%。

| Abstract: | 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%. |
