FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a ...

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 ...

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 ...
