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 ...

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 ...

The new Transformer Bushing Monitor (TBM) system from Serveron, a BPL Global company, permits live power factor testing with no downtime, equipment removal, or off-line tests that fall short of ...

Follow these basic steps to select the best transformer for each phase of your next project. Suppose you've got the job of designing the power distribution for an entire building. At some point, ...

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 ...

Linear Technology Corporation’s LT3798 is an isolated flyback controller with single stage active power factor correction (PFC). Efficiencies greater than 86% can be achieved with output power levels ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management. Understanding the trade-offs between Delta and Wye connections enables ...
