This paper proposes interleaving boost converters ponents and auxiliary active switches to achieve with a single-capacitor snubber to smooth out switch turn-off soft-switching commutation [8]- [9], which would increase transition. The single-capacitor snubber is used to limit rising cost significantly at low or middle levels of power applicarate of drain-source voltage of the switch in the converters for tions. Thus, a converter with passive soft-switching feature reducing turn-off loss. In addition, the converters are operated is more attractive to low power applications.at the boundary of continuous conduction mode and discontinuous conduction mode to reduce turn-on loss, and with an In a single passive soft-switching converter [7], as shown interleaving fashion to decrease output current ripple. As in Fig. 1, the boost converter is equipped with a lossless compared with the counterparts of conventional converter turn-off snubber to reduce turn-off loss and is operated at topologies, the proposed converters have the merits of less the boundary of discontinuous conduction mode (DCM) component counts, higher efficiency over a certain load range, and continuous conduction mode (CCM) to reduce tur-on smaller size, and they are easier to implement. Hardware measurement obtained from experimental prototypes have loss. Due to this operation, inductor current will swing over verified these merits. a wide range. To reduce ripple current and increase power level, two converters operated with an interleaving fashion,
