A new type of direct current sensor was studied which includes magnetic potential self-balance circuit and feedback compensation circuit. The characteristics of the device are simple construction, good stability and reliability, and high precision. A simulation model for new direct current sensor is developed. The simulation results of the system have indicated that the accuracy of the DC sensor is...
A mathematical model for new direct current sensor based on the magnetic potential self-balance and feedback compensation is developed. Theory for the mathematical model is explained. The simulation results of the system are shown that the accuracy of the dc sensor is better than 0.1%
A new type of direct current sensor is developed which includes two parts: magnetic potential self-balance circuit and feedback compensation circuit. The characteristics of the device are: simple construction, good stability and reliability, and high precision (the error less than 0.1% in range of 40%~100% rated current)
