“Cuk Converter” was develped byprofessor Slobodan Cuk from teh California Institute of Technology
Oposite sign!!!
L1 & C2L2 work as filters for the current at the input and the output.
Basic Topology
Intro DescriptionMaterial Analysis TIPS
The basic topology of the circuit comes from the configuration of both, the buck and the boos converter.
