摘要
研究了采用温度系数较低的坡莫合金材料制作的电流采样装置———直流零磁通误差传感器 ,简要分析了它的基本工作原理。该器件重 2 0 0 g ,功率损耗小于 1W ,无温度效应 ,结构简单 ,成本低廉。实测电源电流稳定度在 2 4h内≤ 1× 1 0 - 4。
A zero flux error transductor for the DC power supply with high current stability is developed. The principle is analyzed. The transductor consists of four separate magnetic cores with perm ribbon. As a feed back component the transductor has the following advantages: a small volume and weight (<200 g), power loss≤1 W, low cost, small temperature coefficients. The current stability of the power supply at 40 A is ≤1×10 -4 for 24 h.
