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 ...

Love them or hate them, Nixies are here to stay. Their enduring appeal is due in no small part to the fact that they’re hardly plug-and-play; generating the high-voltage needed to drive the retro ...

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 ...

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 ...
