This whitepaper compares single phase and three phase circuits from the component count, stress level and complexity standpoints. The document shows that on most cases, single phase circuits are the ...

One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric ...

Variable frequency drives (VFDs) are used in many industrial applications to improve energy efficiency and provide precise control over electric motors. By adjusting the frequency, voltage and current ...

The difference between a controller and converter design. Why you want to use a controller versus a converter design. It’s become trendy to multiphase or stack devices as power requirements across ...

The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...
