Figure 1: The Qorvo SiC FET – a ‘cascode’ of a Si-MOSFET and SiC JFET
The performance of wide band-gap (WBG) semiconductor switches such as silicon carbide cascode FETs (‘SiC FET’ henceforth) [1] (Figure 1) and SiC MOSFETs is closely tied to its package. At the pure technology level, nanosecond switching speed and low specific on-resistance result in very low losses, allowing much

The subject of power supplies is potentially very broad and the application of resistors in power supplies is quite diverse. Here we will focus on power supply units (PSUs) designed for use in electronic appliances that nominally require fixed DC outputs ranging from just a few volts up to a few kV.

For more than thirty-five years, the power MOSFET dominated the power management systems due to its constant technological evolution from its device structure to its applications to circuit topologies. However, at the dawn of the new millennium, power MOSFET reached its theoretical limitations that it became un

Different health care applications require different power management solutions. From a power management view, health care is a very interesting market. Though design cycles within health care are quite long, a high level of innovation is fueling the need for new health care electronics. These do not only replac
