磁势自平衡回馈补偿式直流传感器频谱分析

Frequency Spectrum Analysis of DC Sensor Based on the Magnetic Potential Self-balance and Feed-back Compensation

根据磁势自平衡回馈补偿式直流传感机理,得出了磁势自平衡回路的电流波形曲线。通过对电流波形的分析,拟合出描述电流波形的数学表达式,并对其进行了频谱分析,绘制出各次谐波电流均方根值的频谱图。

Based on the magnetic potential self-balance and feed-back compensation,the mathematic expression of the curve of magnetic potential self-balance loop is gained.Then,frequency spectrum analysis is done,and harmony wave chart is protracted.
