Patent ID: 8125802

Claim:
A switch mode power converter system, the system comprising: a first isolation box; a second isolation box; and a plurality of transformer windings including: an input primary winding for receiving an input signal for the switch mode power converter system; an output secondary winding for generating an output signal for the switch mode power converter system; a feedback winding for generating a feedback signal; and a voltage supply winding for generating a voltage; wherein: the switch mode power converter system is configured to convert the input signal to the output signal; the first isolation box includes: one or more first metal boards; and one or more first isolation winding turns; wherein: the one or more first metal boards are conductively connected to the one or more first isolation winding turns; and the one or more first isolation winding turns are not part of any of the plurality of transformer windings; the second isolation box includes: one or more second metal boards; and one or more second isolation winding turns; wherein: the one or more second metal boards are conductively connected to the one or more second isolation winding turns; and the one or more second isolation winding turns are not part of any of the plurality of transformer windings; the input primary winding is substantially enclosed in the first isolation box; the output secondary winding and the feedback winding are substantially enclosed in the second isolation box; and the first isolation box and the second isolation box are biased to a constant voltage.
