Interleaving boost converters with a single-capacitor turn-off snubber

Abstract

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,

Interleaved Boost Converter with Boost-Type Snubber for PV Power System

“…Serious connected, parallel connected and multiphase charging schemes have been proposed to relieve this problem. Besides, they can increase the utility's charging current to further promote the efficiency of battery charger [9,10]. N set of paralleled converters working in interleaved manner can attain an approximately constant current.…”
