[Kerry Wong] had some extreme MOSFETs (IXTK90N25L2) and decided to create a high current electronic load. The result was a two-channel beast that can handle 50 A per channel. Together, they can sink ...

Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the necessity for special electronic loads, ...

When overloads and short circuits occur, there’s always a tradeoff between the power supply shutting down the entire 24 VDC supply and keeping load circuits that aren’t impacted by the failure ...

To help power supply development, semiconductor companies offer evaluation boards which show a typical application of a power-management IC. This gives design engineers the opportunity to start their ...

You use an active-load test circuit to ensure that a power supply for a microprocessor or for other digital loads supplies 100A transient currents. This active load can provide a dc load for a power ...

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 ...
