摘要

This study presents a control strategy and its dynamic analysis of a high-power dc–dc converter, which is constructed with the parallel-connected single active bridge (SAB) dc–dc converters for dc-grid wind farm applications. The structural and operational characteristics of the SAB dc–dc converter have several advantages for high-power applications, and the modular concept of the parallel-connected converter is highly beneficial especially for offshore wind farm applications in terms of maintenance cost and fault tolerance. To justify the feasibility of the parallel-connected SAB dc–dc converter for dc-grid wind farm applications, an input voltage control method based on the PI control will be introduced and the dynamics of the overall system will be analysed. The analysis results are to be verified by means of simulations and experiments.
