N-Stage Coupled-Inductor DC-DC Converter Circuit Diagram #224284 (License: Personal Use)

The diagram depicts a multi-stage resonant DC-DC converter using magnetically coupled inductors, where each stage includes a transformer with turns ratio √Lₖ:1, series leakage reactance jX′ₖ, and mutual coupling coefficient K′ᵢ,ⱼ. Current loops iₖ√Lₖ indicate circulating currents through each inductor pair, while dashed lines denote scalability to N stages. The structure enables high step-up/step-down voltage conversion with reduced switching stress and improved efficiency in high-power applications.

Used in power electronics educational resources, IEEE papers, or engineering documentation to explain multi-stage magnetic integration techniques for isolated DC-DC converters; targets researchers, designers, and students seeking circuit topology insights.
