High-wattage resistors often are used as test loads for power transformers. Resistors don’t introduce phase shifts, and it’s easy to check that a transformer’s voltage regulation remains within spec ...

U.S. utilities need more transformers to build the zero-carbon grid and keep the lights on after major storms. But the specialized equipment is hard to build, and manufacturers can’t keep up with ...

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 ...
