The company has first-class sintered NdFeB production equipment, can produce a variety of brands of sintered NdFeB products, annual production capacity of 500 tons; company has all kinds of finishing equipment, processing of various specifications can be shaped magnetic tile, magnetic ring, The magnetic stripe; company has a comprehensive means test, effectively ensure the product quality.
Aiming at the long design circular period and complex question of multipole magnetized design of NdFeB magnetic ring, the finite element analysis software ANSYS was used to simulate the electromagnetic field when magnetized. The simulated electromagnetic field was analyzed in order to confirm the three parameters by means of adjusting the initial setting parameters of the wire diameter, the coil number and the magnetizing voltage of magnetizing coil. Finally the magnetizing coil was manufactured and magnetized based on these three parameters. And the correctness of the simulation was verified through the test.
Apart from this step, designers should also connect an EMI filter, such as a ferrite bead, to the output of the amplifier.
A second loop, which is one fifth of the diameter of the large loop, is connected to the feedline and this small loop is positioned in the large loop on the opposite side of the tuning capacitor.

A reconnective annihilation of the magnetic field leads to the formation of magnetic flux loop cells with small scales, followed by the enhanced transverse plasmons occurring in the thin current sheet.
Compared with the main circuit of traditional PFC, only several windings are added on magnetic ring and tapped, which effectively suppresses the impact current, reduces the ripple noise and improves the reliability of PFC main circuit. Problems of cusp distortion, output voltage shifting and output voltage regulation with heavy load are analyzed and solutions are given respectively.
