A solid-state transformer (SST) is an AC-AC converter, sometimes called a power electronics transformer (PET), that replaces ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...

Several switching-converter topologies exist for power converters that operate from the ac mains and must maintain a power factor of 0.9 or better. One topology is a boost converter with a control ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

Power factor correction is a frequently misunderstood topic. Improper techniques can result in over-correction, under-correction, and/or harmonic resonance, so it can be helpful to understand the ...

The power factor measurement has long been accepted as an invaluable tool for identifying insulation defects, such as ageing, deterioration, moisture ingress and localized failures, involving the ...

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 ...
