Chokes are important elements in many power electronics circuits, for example in boost converters and current source inverters. Minimizing the choke’s volume and mass is desirable in many applications. This paper considers using a permanent magnet to pre-bias the choke’s core flux as a means of reducing its volume/weight. A methodology for designing a biased choke is presented and potential benefits are quantified through tests taken from a prototype device.
