Abstract
An isolated switching power converter includes a power isolation transformer having at least one primary winding, at least one secondary winding and a plurality of sides, a first power board mechanically coupled to a first side of the transformer, and a second power board mechanically coupled to a second side of the transformer. The first power board includes a primary side circuit electrically coupled to the at least one primary winding, and the second power board includes a secondary side circuit electrically coupled to the at least one secondary winding.
Claims27
An isolated switching power converter comprising:
- a power isolation transformer having a primary winding, a secondary winding and a plurality of sides;
- a first power board mechanically coupled to a first side of the transformer and including a primary side circuit electrically coupled to the primary winding;
- a second power board mechanically coupled to a second side of the transformer and including a secondary side circuit electrically coupled to the secondary winding, the first power board and the second power board including electrical terminals for electrically coupling the first power board and the second power board to one or more other circuit boards;
- and
- a nonconductive cover extending over and around at least portions of the transformer and the first power board, wherein the nonconductive cover is vented adjacent the secondary winding.
