Magnetic amplifiers are made of ferromagnetic materials with nonlinear characteristics and magnetized by direct current and alternating current to carry out power conversion. The magnetic amplifier is mainly used in electrical automatic control system, such as motor speed regulation, voltage regulation, etc. The magnetic amplifier can improve the stability of switching power supply by precise control.
Amorphous and nanocrystalline soft magnetic materials because of the high permeability, high temperature stability, high rectangle ratio and the ideal is applied to magnetic amplifier, the output can provide unparalleled accuracy, and can achieve higher work efficiency, and popularity.
We made the iron-based nanocrystalline soft magnetic alloy material with the magnetic core of magnetic amplifier, switch power supply with high saturation magnetic induction intensity, high square ratio, low coercive force and high Curie temperature, etc. High efficiency, low temperature rise, reset current is small, can be used in a wide temperature range, the working temperature can be as high as 120 ℃.
