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 ...

Various power-converter architectures use their transformer in different modes. In continuous conduction mode (CCM), the magnetic field never completely collapses due to the transformer's mode of ...

A continuous-conduction-mode (CCM) flyback converter is often used in medium power, isolated applications. CCM operation is characterized by lower peak switching currents, less input and output ...

ON Semiconductor is introducing a critical conduction mode ‘bridge-less*’ totem-pole PFC (power factor correction) controller, claiming it to be industry’s first dedicated IC. Called NCP1680, at its ...
