Patent ID: 7042745

Claim:
An DC-AC inverter, comprising: an inverter housing having a receiving compartment and defining an interference zone within which electromagnetic interference occurs, and a free zone free of electromagnetic interference; a power conversion module comprising a main PCB (Print Circuit Board) which has a DC-AC inversion circuitry implemented thereon to convert an input DC signal into an output AC signal and is supported on a bottom wall of said inverter housing within said receiving compartment, wherein a portion of said main PCB is located at said interference zone of said inverter housing and a portion of said main PCB is located at said free zone of said inverter housing; and an interference insulating arrangement, comprising: a DC inlet electrically connected to said main PCB for connecting with a DC power source to draw of a DC current as said input DC signal to said main PCB, wherein said CD inlet is located at said free zone of said receiving compartment to insulate said DC inlet from being electromagnetically interfered during a DC to AC conversion at said power conversion module; and an insulating member disposed between said bottom wall of said inverter housing and said main PCB to insulate said DC inlet with said bottom wall of said inverter housing so as to further minimize said electromagnetic interference of said DC inlet with respect to said inverter housing.
