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 ...

Power-supply designers usually like flyback converters to operate in DCM (discontinuous-conduction mode) rather than in CCM (continuous-conduction mode). In DCM, the flyback converter is a first-order ...

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.
