However if the active clamp flyback converter is designed to operate in CCM, and the duty cycle is controlled to make the input current track input voltage, the input power factor can be improved.

但如果设计反激有源箝位电路工作在电流连续模式，控制占空比，使输入电流跟随输入电压，可以提高输入功率因数。

By using an active clamp circuit, the power transformer core is symmetrically reset. Zero voltage switching conditions are achieved over a broad input voltage and output current range.

利用有源钳位电路实现主变压器铁心对称复位，功率开关在宽输入电压和宽负载电流范围内零电压开关。

Reducing input light power or increasing length and effective area of active layer, we can reduce the SOA chirp;

增加有缘层长度与有效截面面积，也有利于减小SOA的啁啾。
