In this paper, the conducted emission characteristics of an active snubber boost converter with proposed timing diagram are investigated and compared with its conventional boost converter. It is illustrated theoretically and experimentally that the soft switching technique can reduce the high switching dv/dt and di/dt rate, as well as the conducted emission noise spectra generated from the hard-switched counterpart effectively. The presented active snubber boost converter shows the line to ground and the neutral to ground conducted emission spectra significantly be improved at high frequency range over the hard-switched operation.
