DC electronic loads have been available for electronic testing applications for several decades. Today’s products include switched resistors, high-speed active loads utilizing power semiconductors, ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

When it comes to testing power supplies, it’s useful to have a dummy load to put the gear through its paces. While it’s possible to just use some old heating elements or other big resistors, an active ...

The automotive industry demands cost-effective and fully reliable electrical systems, but this tough and potentially destructive environment poses a huge challenge for the power semiconductor devices ...

Bench electronic loads are usually rated for voltages less than 100V, which make it difficult to test high-voltage power supplies. This Design Idea offers an alternative: an inexpensive electronic ...
