ABSTRACT:
An energy transfer apparatus is developed for reducing a conductivity electromagnetic interference and manufacturing method. The energy transfer apparatus comprises a core, an input winding, an output winding, a supply voltage and a supply winding. The supply winding includes a shielding winding and an auxiliary winding. The input winding receives an input voltage for outputting the output voltage through the core and the output winding. The shielding winding and the auxiliary winding generate the supply voltage through the core. By setting of wire size and winding turns of the shielding winding, the conductivity electromagnetic interference is reduced for stabilizing an electric potential between an input-grounding terminal and an output-grounding terminal of the energy transfer apparatus.
