UCC256301做半桥LLC,死区最小可以调到多少?

Other Parts Discussed in Thread: UCC256301, UCC27714

datasheet里面写了minimum dead time =100ns,但又在下面标注了这只是设计数据不是测试数据。想问:1、当其用作LLC的控制芯片 (后面再加上UCC27714作驱动芯片的时候 ),这里所谓的最小死区时间是UCC256301两个输出的占空比的最小死区的意思吗?我怕我英语理解不好。2、作为所标注的设计数据,可采用的保险一点的值是多少?3、为什么官网作为UCC256301的示例LLC电路,谐振腔只有L而不是我们常用的Lr 、Cr 和Lm?
