A adaptive control method of the pulse demagnetizer was presented, Can adjust the strength of the charge current automatically according to the changes of the magnetic content to ensure the constant of the magnetic field.The experimental results have shown that it has the advantages of low power consumption, strong anti-interference capability, stable and reliable operation, long life and good demagnetizing effect, when compared to the conventional demagnetizers.
The design of long-life, high-efficiency PEM fuel cell power supplies for low power sensor networks
