Most boost converters with PFC may operate in either discontinuous mode or continuous mode. In discontinuous mode (see the figure, a), the switch is turned on when the inductor current reaches zero ...

Flyback transformers come in two flavors: CCM (continuous conduction mode) and DCM (discontinuous conduction mode). The DCM version is the one we will develop here. The idea of the DCM flyback is that ...

UCC28180 is ideal for universal AC input systems that operate in a range of 100-W to a few-kW, with the switching frequency programmable between 18 kHz and 250 kHz. It conveniently supports both IGBT ...

The definition of power factor (PF) is the ratio of the power drawn from the power grid (apparent power) to the power actually consumed in the load (real power). A power factor of ‘1.0’ is defined as ...
