【摘要】 采用一种新型双向DC/DC变换器的拓扑结构,将软开关技术和移相PWM控制技术以及双向DC/DC变换器技术有机结合起来,有效地降低了电路的开关损耗和开关噪声,为双向DC/DC变换器提高开关频率、效率以及降低尺寸及重量提供了良好的条件。同时,还保持了常规的硬开关全桥PWM双向DC/DC变换器拓扑结构简洁、元器件电压和电流应力小等一系列优点。更多还原

【Abstract】 A novel bi-directional DC/DC converter is introduced. The soft-switching,phase-shifted PWM and bi-directional DC/DC converter hang together,depress circuit switch ullage and noise effectively, which provide condition to increase switch frequency,efficiency and reduce size and weight for the converter; at the same time, the converter has the virtue of structure compact, voltage and current stress small etc, such as ordinary hard switch converter.更多还原
