Many loads are mainly resistive; thus, they’re rated in watts (i.e., true power). Simply stated, these loads have a very small reactive component, which means an apparent power rating (VA) would not ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

With the rapid development of power electronic devices and the urgent need for ship electrification, the medium voltage direct current (MVDC) integrated power system is regarded as the development ...

In olden days, when op amps used ±15 V supplies and input/output signals were ±10 V, we had few problems with input/output limitations. Our op amps output impedance (Zo), small-signal AC impedance, ...

Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the necessity for special electronic loads, ...
