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 ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

Industrial and commercial customers constantly scrutinize their monthly electrical usage, looking for ways to save money. Installing power factor correction capacitors can reduce costly penalties ...

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 ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...
