ZVS - Opis:
- Luo converter is one amid the developed DC-DC converters offering higher voltage gain. Soft-switching techniques, like zero-voltage switching (ZVS), repress switching losses, and hence the system efficiency and the life of the power semiconductor switches are improved. Incorporation of soft switching in fixed-frequency operation of the Luo converters may persuade them in the regulated power supply applications. The existing variable switching frequency solution suffers from a number of problems viz. complexity in filter designing, more electromagnetic interference (EMI), etc. This paper proposes a positive output elementary Luo converter (POELC) involving ZVS with the wherewithal of working in fixed frequency. A comprehensive discussion on the proposed circuit topology is detailed with both simulation and experimental studies. Systematic descriptions of basic POELC, variable-frequency ZVS-POELC, and fixed-frequency ZVS-POELC make an impact on the understanding of related concepts by the researchers in this field.
