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 ...

Testing bench power supplies would require the use of a current build and the best way to have one is to build yourself one. The article shows how a custom dummy load is built. Testing bench power ...

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 ...

Like most engineers, I have used dummy loads spanning DC through RF, and from a few watts to hundreds of watts. Most of these loads were built up from basic resistors, and in some cases special ...
