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 ...

From our discussion in last month's Power Design column, we know that low cost and simplicity are the major advantages of the flyback topology. In multiple output applications, the addition of a ...

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 ...

A novel approach to power factor correction in switching power supplies that works by controlling both on and off time of the switcher, based on inductor current. Fig 1.The disadvantage of the CCM ...
