![]() ![]() Unfortunately, with magnetic hysteresis comes hysteresis loss in a transformer. If you want to plug anything into the wall and receive grid power, there are some important requirements you’ll need to satisfy, one of which relates to hysteresis in a transformer. They step up or step down AC voltage/current to useful levels, which then can be converted to DC and used to power your favorite electronics. Transformers are one of those important pieces of equipment that make modern life possible, as they provide a critical power conversion function. ![]() The magnetic core in this transformer will create hysteresis loss at high input current and magnetic field. To prevent distortion, transformers that are used for power electronics should be chosen so that they do not strongly saturate at the input magnetic flux value. Magnetic materials in the core will eventually become magnetically saturated when they are placed in a strong magnetic field, such as the magnetic field generated by an AC current. Hysteresis loss in a transformer occurs due to magnetization saturation in the core of the transformer. ![]()
