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 ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

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 ...

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 ...

As the push to move beyond the easy-to-find sources of energy inefficiencies intensifies, a key area to investigate is the power factor of your facility and the impact your automation devices have on ...

Your utility Power Factor is the ratio of the system’s Real Power and the Apparent Power (Eq. 1, Fig. 1). This unitless factor ranges from −1 to 1. The Power Factor ratio aptly describes the type of ...
