The application and research of integrated magnetic technology in switching power supply

With the increase of small magnetic devices, and high-frequency magnetic technology improving, integrated magnetic technology as a magnetic device can improve the power density, volume decreased magnetic pieces of the application of modern technology is in the power electronics plays an increasingly important position, increasingly extensive research. This paper introduces the magnetic circuit model pieces of the establishment, and application researches of integration magnetic technology on the high-power high-frequency switching power supply.
