Abstract
A DC-to-AC inverter includes an inverter housing, a power conversion module, and an interference insulating arrangement which includes a DC inlet and an insulating member. The inverter housing has a receiving compartment defining an interference zone within which electromagnetic interference occurs, and a free zone free of electromagnetic interference. The power conversion module includes a main PCB which has a DC-AC inversion circuitry implemented thereon to convert an input DC signal into an output AC signal. The DC inlet is electrically connected to the main PCB for connecting with a DC power source to draw of a DC current as the input DC signal to the main PCB, wherein the CD inlet is located at the free zone of the receiving compartment to insulate the DC inlet from being electromagnetically interfered during a DC to AC conversion at the power conversion module.
