This constant resistance dummy load has not yet been tested in the real world. [YS] was inspired to come up with the circuit after reading Wednesday’s Re:load dummy load post. That was a constant ...

Here is a nice hack you may find very useful if you have a cheaper bench power supply that supports constant current limit protection (CC mode) and the only way to set or check your max current limit ...

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 ...

Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests the ...

How do you deliver constant power when the load impedance isn't constant? That problem arises, for example, in trying to maintain a warm LCD display on an outdoor gas pump in cold climates. As the ...

Thus far we have devoted our attention to the study of constant-potential transformers, for which the load voltage is essentially constant and the current varies with the load. A transformer of this ...

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 ...
