Abstract

The potential of a microinductor utilizing a thin film magnetic alloy magnetic component is investigated via a simplified optimal design procedure. A well-established solenoid geometry is utilized to compare commercially available and electrodeposited alloys. Analytical and experimental analysis is concerned with the MHz frequency range for dc-dc converters. Inductance values ranging from 0.3 ?H to 120 ?H with component power efficiency above 90% have been measured. An optimal design process is developed based on preliminary data providing a device with a power density of 28 W cm^-3 and power efficiency of 94%. © 2006 IOP Publishing Ltd.
