Abstract

Non-Grid-Connected Wind Power is directly applied in High Energy-Consuming Industry through simple transformation, which avoids Grid-Connected problem on a certain extent. A combined input-series output-parallel (ISOP) DC/DC converter, which contains the composite structure of full-bridge (FB) DC/DC transformer and FB DC/DC converter, is studied. The modular design of the converter is realized. The circuit structure and the control strategy are simplified. To realize safe and reliable operation of the combined ISOP-FB DC/DC converter, the input voltage and output current of the converter must be controlled within permissible errors. An ISOP simulation model and principle prototype is built. The simulation and experimental results verify the theoretical analysis.
