with the development of high frequency and miniaturization of power supplies, design requirements are higher for the power transformer, the core component of electromagnetic conversion of high frequency power supplies. high-frequency transformers must meet the requirements of high frequency, low loss, small volume, high energy efficiency conversion efficiency and size customization.
at present, a large number of ferrite core transformers are used in the high-frequency power supply market, but their major problems are large volume, high temperature rise, low temperature conversion efficiency, poor resistance to unbalanced current characteristics, high temperature input impedance characteristics fluctuations and high temperature leakage inductance, which affect the electromagnetic compatibility of the circuit and the normal resonant working state.
in recent years, nanocrystalline have been updated iteratively. and ultra-thin ribbon has been developed vigorously to meet the development trend of high frequency which can basically meet the design requirements of high frequency transformers within 100 khz. nanocrystalline soft magnetic alloy materials have the advantages of high saturation magnetic induction, low loss, high power size customization design and high temperature operation reliability. it has been favored and praised by design engineers in the field of high-frequency power at home and abroad.
high saturation magnetic induction intensity—reduce the size of the transformer effectively
low coercivity—to improve the efficiency and reduce the transformer exciting power and copper loss
permeability- customized design according to your needs
low loss- reduce transformer temperature rise
higher curie temperature - excellent temperature stability
high-power design - to meet the needs of large-size iron core customization
