【应用】R6576ENZ4C13功率MOSFET助力3KW 5G通信电源LLC高功率密度设计
图1是3KW的5G通信电源的主架构框图。其中主体是由整流+PFC+逆变(LLC)+同步整流搭建而成。LLC主要是采用MOSFET配合电容电感作为逆变电路,与同步整流的供电端实现能量转换。
图1:基于R6576ENZ4C13功率MOSFET的3KW 5G 通信电源主架构框图
基于3KW的5G通信电源追求高功率密度特性。LLC选型时的MOSFET导通压降要求尽可能的低,这样才能实现开关频率提升的情况下降低系统损耗提升效率,或者同样的损耗条件下减小散热器的体积。另外当开关频率提升后,后端感性器件可以相应的减小,从而实现小型化设计,进而提升整体产品的功率密度。故LLC的MOSFET在满足电流规格下的导通电阻是越小越好。
ROHM的R6576ENZ4C13功率MOSFET(图1的框图中逆变的位置),650V/76A的MOSFET。R6576ENZ4C13的RDS(on)标准值是40mΩ,最大值才46mΩ。它的导通电阻非常低,在10A应用稳态常态电流下,相当于最大0.46W的功耗。故R6576ENZ4C13在3KW的5G通信电源LLC应用上可实现低损耗设计。
Rohm的R6576ENZ4C13功率MOSFET的主要应用特点:
1:导通电阻低,实现低导通损耗。由Figure11的RDS(on)-ID关系曲线可以看出。在VGS=10V的条件下,导通电阻与电流是正比关系,当电流30A以内时,导通电阻的曲线是几乎是平的,电流超过30A~76A,导通电电阻的变化也是非常的小,故该MOSFET在规格内导通电阻的阻值随着电流的增大的变化率非常低,大电流应用下依旧可保持高效特性。导通电阻小,MOSFET可开通过开高频,减小周边器件体积,这样在降低功耗的同时实现整体产品小型化。
2:Q g低至260nC。Qg*RDS(on)是MOSFET产品品质的体现。另外根据Qg=I*t的关系式,同样的驱动电流I的情况下,Qg越低,代表整体开通的时间越短,上升的曲线就越快,开通的损耗也就越小。
3:低反向恢复损耗。由Fig.4-1和Fig.4-2可以看出反向恢复对MOSFET在LLC应用的损耗影响。而R6576ENZ4C13反向恢复时间Trr短为990ns,反向恢复的Q rr低至32μC,该MOSFET应用时的反向恢复损耗低,LLC设计应用时可提升设计产品的效率。
