Abstract Scope |
Inductors are a very common component in many power electronic systems. In these systems inductors typically take up a large portion of the total volume, mass, and losses. If an inductor is utilized with unidirectional current flow, then volume and mass may be substantially reduced by biasing the magnetic flux within the inductor core using permanent magnets. Such inductors can effectively double the core utilization of a traditional inductor. Permanent magnet biased inductors are therefore much smaller and lighter than equivalent unbiased inductors. Related applications include filters, unidirectional non-isolated power converters, and inrush current limiting devices. |
