Abstract:

提出一种高增益交错耦合电感直流-直流升压变换器,适用于低输入电压、高输入电流的低压可再生能源发电系统应用场合,如光伏/燃料电池发电系统。该变换器在输入端把两个耦合电感的原边电流进行交错并联,减小了输入电流和输出电压纹波;两个耦合电感的副边串联后再与一电容相结合组成倍压单元,进一步提高变换器的电压增益。该电路结构中,使用两个交错串联的输出电容,它们既能回收利用耦合电感的漏感能量,又能钳位开关管的漏源电压,减小开关管电压应力,因此,有利于选择低导通电阻、高性能的开关器件以进一步减小功率管的开关和导通损耗。另外,耦合电感的漏感可使主开关管零电流开通,同时漏感也能控制二极管关断电流的下降率,大大减轻二极管的反向恢复问题。论文详细分析所提变换器的工作原理和稳态特性,最后通过一台实验样机验证了理论分析的正确性。
