一种用于可再生能源应用的半二次反向高升压DC-DC变换器

A new high step-up dc–dc converter that is suitable for renewable energy systems is proposed in this article. By integrating a three-winding coupled-inductor (CI), a semiquadratic configuration is established for considerably enhancing voltage gain by the CI turns’ ratios, in addition to the converter duty cycle. Furthermore, a passive clamp circuit is integrated to recycle the leakage energy and ...
