Abstract :
This paper presents the feasibility study of zero current soft-switching (ZCS) PWM boost DC-DC converters with auxiliary lossless active edge-resonant cells. This type of soft-switching DC-DC boost converters is effective especially for IGBTs-based DC-DC converter due to its commutation process independent on the tail current transitions. The performances of ZCS-PWM DC-DC converter topologies are compared by experimental data, referring to the hard-switching one, and detailed investigation including loss analyses is described in order to demonstrate the practical feasibility of the active edge resonant cells.
