摘　　要：DC/DC变流器在高输入电压的场合可以采用输入串联输出并联(ISOP)的拓扑结构,通过分析该拓扑输入均压与输出均流之间的关系,得出保证输入均压是保证该拓扑可靠运行的关键;针对负载为蓄电池特性的电源装置,研究了一种双电压环控制策略,并且已经在实际产品上得到了验证。An input-series and output-paralleled （ISOP） circuit topology was very suitable for high input voltage to DC-DC conversion application. Relationship between the voltage sharing and the current sharing of ISOP topology was analyzed, which was concluded that the key question of IOP topology was to ensure the voltage sharing of the input divided capacitors of each module. A kind of double voltage loop control strategy was studied for the battery power supply unit, which was verified by actual products.
