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 ...
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 ...
A peak current-mode power supply is subject to subharmonic oscillations if two conditions are met: the converter operates in the continuous conduction mode (CCM) and the duty-cycle is close to or ...
