Zhou Hongqiang · Electrical Measurement & Instrumentation · 2009
The circuit for testing system of magnetic performance is introduced in this paper. The testing system completes the drawing of the magnetic hysteresis loop and the testing of magnetic parameters. The testing system is mainly composed of sine wave signal generator,signal processing circuit,signal sampling and transferring circuit and so on. The system is simple,reliable and easily implemented. It contributes to the testing system of magnetism for the development of higher precision,lower cost and easier use.
