Abstract :
Fabrication of a high-frequency power transformer/inductor using multilayer thick-film hybrid technology is presented. An experimental 6 MHz, 40 W miniature transformer is fabricated with windings printed on the ferrite substrate. Half of a conventional low-profile pot core is used to close the magnetic path. Issues related to power density, thermal management, and efficiency of this hybrid power-magnetic integrated circuit (HPMIC) are discussed
