摘要
采用有源箝位复位方式能够有效提高变换器的效率,然而箝位开关管的增加提高了控制电路的难度,文章中设计了一种简单的驱动电路,解决了开关管之间的延时问题,实验结果证实该方案有效提高了变换器的效率。
The reset mode of active clamp can improve the efficiency of forward converter,but it makes the whole control section more difficulty because of the addition of the clamped switches.In this paper,a new driven circuit was designed,the problem that delay time between two switches is solved by this new method.The test results verify that this method can improve the efficiency of forward converter.
