Every switch-mode power supply presents a wide-band noise source. Integrating a DC/DC converter from the car board net into an automotive control unit and still fulfilling the EMC requirements of ...

Fundamental to careful system design of any DC/DC power converter is a well-planned and carefully executed printed circuit board (PCB) layout. An optimized layout leads to better performance, lower ...

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

Find a downloadable version of this story in pdf format at the end of the story. Although features and functionality attract the most attention for new electronic products, whether consumer, ...

Part II of Art. 690 provides the circuit requirements for PV systems. The first requirement it covers is the maximum PV system direct-current (DC) circuit voltage. This value is used when selecting ...

Researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) are breaking technical barriers with faster circuit breakers to enable and protect the modern electric grid. The ORNL ...
