Indirect sliding mode adaptive fractional order nonlinear observer based controller with fractional order single-ended primary inductor converter

International Journal of Electrical Power & Energy Systems
Direct Current to Direct Current (DC/DC) converters like the SEPIC (Single-Ended Primary-Inductor Converter) use both passive and active components to control the system via a duty cycle. The SEPIC converter is non-inverting and can both step up and step
