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 ...

This constant resistance dummy load has not yet been tested in the real world. [YS] was inspired to come up with the circuit after reading Wednesday’s Re:load dummy load post. That was a constant ...

Power resistors, rheostats (variable resistors), and other electrical loads are useful for testing power supplies and regulators. Though functionally equivalent to a mechanical rheostat, electronic ...

An array or bank of load resistors is often required for testing power products, characterization of solar panels, and many other applications that require evaluation under various well-defined loads.

The simplest model of a battery comprises an ideal voltage source that connects in series with a resistance whose value—often a few milliohms—depends on the battery’s electrochemical condition and ...

Insulation failure is the root cause of many electrical conductors and equipment failures. When insulation fails, not only can equipment be damaged, but fire and shock can also result. Ideally, when ...

Understand and comply with relevant codes and standards such as NFPA 70B, NFPA 79, and NEC 110.7 to ensure proper insulation testing procedures. Develop a comprehensive job safety plan that includes ...
