| 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 采用非互补导通控制,在ccm模式下由于功率管电流峰值和有效值的减小,逆变器变换效率较dcm模式下有所提高;另外, ccm模式下,反激逆变器采用同步整流控制,减小了整流二极管的导通压降,并且电路中同步整流管可实现零电压开通。 |
