Abstract:
1. A power converter including an input and an output, comprising: a rectification circuit, coupled to said input, including a first magnetic circuit element including a first primary winding and a first voltage-sensing winding, and a second magnetic circuit element including a second primary winding and a second voltage-sensing winding, said first and second primary windings coupled in series and to said input, said first and second voltage-sensing windings coupled in series, each of said first and second voltage-sensing windings having a polarity to produce a scaled difference of voltages applied to said primary windings, wherein said first voltage-sensing winding is coupled with an opposite polarity to a polarity of said first primary winding; an inductor coupled in series with said voltage-sensing windings; and a capacitor coupled in series with said inductor and said output.
