1. An AC-DC converter, comprising:

  • at least two half-bridge current doubler rectifiers (CDRs), each of which is driven with a respective AC drive voltage and is arranged to provide two rectified output currents to an output node, said AC drive voltages having a switching period Ts,a filter capacitor connected between said output node and a common node coupled to an output of said converter, anda load connected between said output node and said common node,said AC drive voltages arranged such that they are phase-shifted by Ts/(2*N) such that the rectified output currents of said at least two CDRs are interleaved, wherein N represents a number of said CDRs.
