High frequency transformers used in auxiliary power supplies for railway locomotives, insulated power converters, inverter welding machines, etc. High-frequency step-up transformers used in high-voltage power supplies for medical equipment and electrostatic de-dusting equipment.
Manufacturing with low loss, high saturation flux density Nanocrystalline soft magnetic materials helps to reduce losses in high frequency transformers and to reduce size and weight (compared to Mn-Zn ferrites, Table 9.1).
