While testing the power supplies or discovering their potential problems, you must apply dynamic and static tests. This circuit, namely current sink, makes this job easier for you. It can draw 0 to ...

Power supplies for high-voltage applications such as x-ray tubes, e-beam welding, and pulsed radar have some things in common with those for low-voltage applications. There are also important ...

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 ...

It couldn’t be simpler but you have to admit that a small adjustable portable power supply like this one will be really handy. The main part of the PSU is an LM317 linear voltage regulator which we’re ...

Electric motors that are either poorly maintained or which lack the proper electrical protection are the second greatest cause of electrical fires. So says the Factory Mutual Research Corp., a ...

Don’t get zapped when buying a new high-voltage DC power supply. Understand the specifications first. Lasers, linear accelera-tors, X-ray machines, defibrillators, radar, and numerous other ...
