Comparators are subject to input offset errors that can be either systematic or layout related. Two applications of comparators in a PWM controller are detecting when there is no current in the ...

For the PDF version of this article, click here. Let's return to the question, “Why Have an Air Gap?” initially posed in the Power Design article in the December 2002 issue of Power Electronics ...

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 ...

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 ...

This course introduces more advanced concepts of switched-mode converter circuits. Realization of the power semiconductors in inverters or in converters having bidirectional power flow is explained.

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 ...
