FIXED-FREQUENCY BUCK-BOOST ZERO-VOLTAGE-SWITCHED QUASI-RESONANT CONVERTER

The paper presents the analysis and design of a fixed-frequency buck-b oost zero-voltage-switched quasiresonant converter topology. Although the analysis of such a converter presents some difficulties that do no t exist in other converter schemes, the aim of the paper is to point o ut and investigate these difficulties and to provide a design example with experimental results that verify the theory.
