标题[请益]看书时遇到的疑惑
时间Thu Jun 9 14:54:55 2011
Fundamentals of Power Electronics此书的第119页有段文字写说:
Unlike the buck converter, the boost converter must operate in the continuous
conduction mode near D=0 because the ripple magnitude approached zero while
the dc component I does not.
其中the ripple magnitude approached zero while the dc component I does not
是代表什麽意思
请懂得大大帮忙解说，谢谢

1F：→ gp1288:我猜是这个意思，根据前页的公式5.30，Boost转换器在D=0时 06/10 13:30
2F：→ gp1288:是没有电流涟波的，所以一定是CCM 06/10 13:32
3F：→ gp1288:而Buck转换器则是没有任何直流成份的电流? (我英文很菜) 06/10 13:37
