As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...

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 ...

Figured this was the best place to put it.<BR><BR>I'm making 50 ohm RF dummy load with resistors. So I'm using 0.5W metal film resistors in parallel, a fair few of them.<BR><BR>I have 49.9 ohms ...

This is an exciting day for me — we finally get to build some ham radio gear! To me, building gear is the big attraction of amateur radio as a hobby. Sure, it’s cool to buy a radio, even a cheap one, ...

I'd like to ask if it's safe to use a PSU to just power CCTV Cameras and recorder (which uses 12v) without using a computer. (are there things i should watch out if i do this like using dummy loads ...
