The design challenges for a high-power electronic load extend beyond the electronics. The best electronic load circuit will not function well without a good connection to the device under test. The ...

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 ...

This project is made out of few junkbox parts and builds a useful constant current load for switch mode power supply, battery testing, and other applications. A dummy load is traditionally a big ...

This article is adapted from a presentation at TestConX, March 5-8, 2023, Mesa, AZ. A power-delivery network (PDN), also called a power-distribution network, is a localized network that delivers 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 ...
