Magnetic flux selection of 0.2mm silicon steel sheet
Silicon steel sheet should not be used as medium or high frequency transformer, its limit frequency is 400HZ, because the higher the frequency of silicon steel sheet, the greater its loss, it will heat. Therefore, silicon steel sheet is only used as power frequency transformer.
If you want to do it, you can only make it very low. Specific can be taken, according to the specific silicon steel sheet in 400HZ at the corresponding magnetic density of the loss to calculate its heating.
To do if transformer 400Hz, non special needs, still uses the silicon steel sheet core; due to the work of the 400Hz, the core unit loss is many times larger than 50Hz; flux density determination is not only related to the number of windings of the transformer, but also related to the core size, weight loss and temperature rise, and transformer the efficiency of the whole temperature performance and cost.
