A New Structure for Nonisolated Boost DC-DC Converter.

In this paper, a new structure of nonisolated boost DC-DC converters is proposed. The operation of the proposed structure in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) is presented. Then, the critical inductance relation between CCM and DCM is obtained. The voltage gain and current stress of switches are calculated. Finally, the validity of the presented theoretical issues is reconfirmed by using simulation results obtained from PSCAD/EMTDC software. [ABSTRACT FROM AUTHOR]
