The SSC2001S, developed and released by Sanken since 2012, is a continuous conduction mode (CCM) control integrated circuit (IC) designed for power factor correction (PFC). This device has a low peak ...

An industry-first FAN9673 is an interleaved continuous conduction mode (CCM) PFC controller that enables high power PFC control using the smallest possible inductors and lowest possible power rating ...

变压器初级电感电流工作在连续导通模式CCM Continuous Conduction Mode，每个开关周期结束时，电感电流没有降到0，而是降到某一个电流值ILp(min)；每个开关周期开始时，电感电流从初始值ILp(min)开始增加。每个开关周期开关管关断时，电感储存能量，并没有完全释放。

1）CCM（Continuous Conduction Mode），连续导通模式：在一个开关周期内，电感电流从不会到0。或者说电感从不“复位”，意味着在开关周期内电感磁通从不回到0，功率管闭合时，线圈中还有电流流过。 2）DCM，(Discontinuous Conduction Mode)，断续导通模式：在开关周期内 ...

Some applications require a positive voltage to be generated from a negative input voltage. This can be done either by using a transformer based topology, such as a flyback converter, or with a ...
