| 摘要 |
<p>The invention relates to an electric converter operating on the principle of an isolating transformer or flux converter, in particular a switching power supply and/or line transformer for a television set, having an essentially closed, multi-limbed core in which one or more permanent magnets are inserted outside points surrounded by coils in the path of the core. The permanent magnets and, if required, an air gap, are of such dimensions that, outside the near field, the orders of magnitude of scatter fields of comparable converters having no permanent magnets are not significantly exceeded. The permanent magnets preferably have a height of approximately 0.3 mm, the air gap having a height of approximately 1.3 mm. A nominal power increase of approximately 50 % is achieved compared with the said converters.</p> |
