2. Compare to the operation under the dcm mode , the power switches of the inverter under the ccm mode has lower peak current and rms current , so the efficiency can be improved . as the synchronous rectification strategy can reduce the conduction losses of the rectifier , and also due to the zvs realization of all synchronous rectifiers , the
   采用非互補導通控制,在ccm模式下由于功率管電流峰值和有效值的減小,逆變器變換效率較dcm模式下有所提高;另外, ccm模式下,反激逆變器采用同步整流控制,減小了整流二極管的導通壓降,并且電路中同步整流管可實現(xiàn)零電壓開通。
3. The principles and characteristics of synchronous rectification ( sr ) are given , and advantages of self - driven sr in low power applications is detailed . review of several topologies which incorporate self - driven sr makes the constrains of conventional self - driven sr scheme apparent and thus a new scheme to drive srs is proposed . the developed single - winding self - driven synchronous rectification ( swsdsr ) scheme works properly in topologies that drive symmetrically the transformer ( push - pull , half bridge , . . . ) . it allows for maintaining the srs on even when the voltage in the transformer is zero , which is impossible to do in traditional self - driven approaches
   本文針對低壓/大電流輸出的小功率dc / dc變換器，圍繞著變換器的效率問題，分析了同步整流的原理和特點，重點闡述了自驅動同步整流在低功率場合的優(yōu)勢，在分析比較了多種與自驅動同步整流相結合使用的電路拓撲后，指出常規(guī)的自驅動同步整流方案限制了與之結合使用的電路拓撲的范圍這一局限性，從而給出了一種新穎的單繞組自驅動同步整流方案。
4.
