摘要
介绍了一种固定关断时间控制的功率因数校正电路,它的主要特点是通过外部简单电路来控制开关管的关断时间,从而实现了固定关断时间,这样可以提高输出功率等级。实验表明:这种控制方法实现了固定关断时间控制。
A fixed-off-time-controlled PEG circuit is introduced. It has some traits: the off-time of the switch is controlled through a external sample circuit to achieve the fixed-off-time, it will increase the output power. Experiment results show that the off-time is fixed.
