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 ...

In [Dave’s] latest episode of the EEVblog he takes a look at constant current dummy loads. These are used to test power supply designs and instead of just chaining resistive loads together every time ...

The sound produced by any given electric guitar is shaped not just by the instrument itself but by the amplifiers chosen to make that sound audible. Plenty of musicians swear by the warm sound of ...

I sold low-power FM transmitters in a former job, and one of the things I learned is that most customers lacked a suitable dummy load for testing. In new LPFM or translator applications, you can save ...

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 ...

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 ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.
