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 ...

[tinfever] needed a high-power benchtop electronic load for an upcoming project, and by their own admission decided foolishly to build their own. And we’re glad they did. The thing is, whilst this isn ...

The trend in commodity chip resistor sizes is to go smaller. Just like semiconductors, the smaller the resistor the more you can get from a single ceramic sheet during manufacturing. However, it is ...

Figure 1 shows the schematic diagram of the device. The design consists of two main parts: the main regulator circuit and the current-limiting circuit. IC3 is the LM338 5A positive linear regulator. 1 ...

Figure-1 shows the schematic diagram of the device. P1 is used to connect the 220V-AC input and the ON/OFF switch to the circuit. C1 is used to reduce the AC voltage. The value of the C1 also ...

While it might seem counterintuitive on the surface, there are a number of cases where dumping a large amount of energy into a resistor simply to turn it into heat is necessary to the operation of a ...

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 ...
