在电量测量中,按“偏转法”原理工作的不平衡式电桥,桥路对角线(负载端)有信号电压输出,因而去掉了平衡电桥的调零环节,从而改进了后续电路,动态性能良好,既可用于静态测量,也适用于动态测量。本文则着重讨论了不平衡式测量电桥的电压灵敏度和非线性误差。 In the power measurement, according to “deflection method ” principle of unbalanced bridge, the bridge diagonal (load side) signal voltage output, thus eliminating the balance of the bridge zeroing process, thus improving the follow-up Circuit, good dynamic performance, both for static measurement, but also for dynamic measurement. This article focuses on the unbalanced measuring bridge voltage sensitivity and nonlinearity error.
