ABSTRACT:
An inverter (10) includes a circuit board (20) including a transformer (40) disposed thereon, and a shield cage assembly (60) for enclosing the transformer. The shield cage assembly includes an insulative cage (602) defining an inner receiving space (6028) for receiving the transformer, a first conductive cage (604) defining a first receiving space (6048) for receiving the insulative cage, and a second conductive cage (606) defining a second receiving space (6068) for receiving the first conductive cage. The shield cage assembly blocks EMI emitted by the transformer from interfering with electronic components out of the shield cage assembly, thus enabling the electronic components to perform more reliably.
