Power diodes, power MOSFETs, and IGBTs are explained, along with the origins of their switching times. Equivalent circuit models are refined to include the effects of switching loss. The discontinuous ...

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 ...

But conduction losses make discontinuous mode undesirable for converters that have to supply more than around 200 W. "The kind of PFC you use depends on the power level," says Stephen Oliver of ...

Established models exist for both current- and voltage-mode switching buck converters. For this model, you assume sufficient load current so that the current through the inductor is continuous. If you ...

Linear Tech has brought out a synchronous current mode monolithic buck-boost converter that delivers up to 5A of continuous output current in buck mode from a wide variety of input sources, including ...

The boost switching regulator operates in either CCM (continuous-conduction mode) or DCM (discontinuous-conduction mode). It is easier to set up a circuit for DCM operation (Reference 2 ). The name ...

Linear Tech has brought out two synchronous current mode buck boost converters that deliver up to 600mA of continuous output current from a wide variety of input sources, including single- or multiple ...
