变频软开关及优化负电流的四相交错耦合双向DC-DC变换器
Four-phase Interleaved Coupled Bidirectional DC-DC Converter with Variable-frequency in Soft Switching and Optimization of the Negative Current
摘要
Abstract
Aiming at single-phase half-bridge bidirectional DC-DC,its operational modal and resonant process were analyzed in Buck mode.The control strategy to implement variable-frequency in soft-switching was discussed;Discussion on soft-switching and optimal negative current control when the high side and low side work in different circumstances of Buck mode of the single-phase half-bridge bidirectional DC-DC was carried out;A four-phase interleaved soft-switching bidirectional DC-DC converter of optimization negative current variable-frequency control with combination of coupled inductor was proposed.Experimental results show that,compared with fixed-frequency control,the new variable-frequency and optimization of the negative current control strategy improves converter efficiency greatly,improve the inductor current ripple.关键词
