Transformer core refers to a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials.
Silicon steel and FeSiAl materials have high saturation magnetic induction values Bs, but their effective magnetic permeability values are low, especially in the high frequency range;
Permalloy has high initial permeability, low coercivity and loss, and stable magnetic properties, but Bs is not high enough. When the frequency is greater than 20kHz, the loss and effective permeability are not ideal, the price is more expensive, and the processing and heat treatment are complicated.
Co-based amorphous alloy has high permeability, low Hc, low loss in a wide frequency range, close to zero saturation magnetostriction coefficient,
insensitive to stress, but low Bs value and expensive.
The greater the power of the transformer. The coils can be installed on both sides of the core, so the number of turns of the transformer can be allocated to the two coils, so that the average turn length of each coil is shorter and the copper loss of the coil is reduced. In addition, if two coils that require symmetry are wound on two coils respectively, a completely symmetrical effect can be achieved. A set of silicon steel sheets composed of four C-type silicon steel sheets is called ED-type silicon steel sheets. The shape of the transformer made of ED-type silicon steel sheets is flat and wide. Under the same power conditions, the ED transformer is shorter than the CD transformer. Larger, in addition, because the coil is installed in the middle of the silicon steel sheet, there is an external magnetic circuit, so the magnetic leakage is small, and the overall interference is small. However, all the coils are wound on a wire package, which is thicker, so the average turn length is longer , The copper consumption is relatively large.
