Hybrid Phase Shift Control Strategy for High-frequency DAB Converter Based on Multi-objective Optimization
随着双有源全桥(dual active bridge,DAB)变换器开关频率的提升,半导体器件的开关损耗占比越来越大,基于回流功率、电感电流峰值或有效值的单目标效率优化策略的优势逐渐丧失.为提升DAB变换器的高频工况运行效率,文中对DAB最优模态与优化目标进行定量分析与选择,提出一种可同时实现电感电流有效值准最优、宽范围软开通的移相策略,在该策略下轻重载工况所有开关管均可实现软开通,中载仅有两个开关管丢失软开通.为保证软开通的有效实现,根据电荷交…查看全部>>
With the increasing of the dual active full bridge(DAB)converter's operating frequency,the proportion of active semiconductors'switching loss is prominent,resulting in the fact that the single-objective optimization strategies based on the backflow power,peak or RMS inductor current are gradually losing the efficiency advantages.To improve the high-frequency operation efficiency,this paper carries out a quantitative analysis of optimal operation modes and op…查看全部>>
