| Abstract: | Reviews recent progresses in topologies and applications of low-voltage high-current converter.By analyzing and making comparison of the topologies in the primary and secondary side of the converter,the article elicits the appropriate topologies for isolated low-voltage high-current output DC/DC converter.The symmetrical half bridge with the current double rectifier topology,push-pull forward topology and integrated-filter push-pull forward topology are illuminated. Synchronous rectifying teehnology is introduced as well. |
