Abstract:
A ripple reduction circuit for use in a current doubler rectifier has first and second inductors coupled via a first coupling coefficient. The first and second inductors generate a first and a second ripple current, respectively. A third inductor is coupled to the first and second inductors; and an impedance is connected in series with the third inductor, wherein the circuit generates a third ripple current opposing the combination of the first and second ripple currents generated by the first and second inductors.
