A follow-up to the article “Design a PFC Resonant Coupled Inductor That Doesn’t Distort Power Factor” (July 2015) described the design of the resonant inductor. This article describes how ...

In its latest monthly column for pv magazine, IEA-PVPS provides a comprehensive overview of the state-of-the-art practices, best practices, and recommendations for managing reactive power amidst the ...

Kehua has announced that its SPI series 1500V/350kW string inverter has passed High Voltage Ride Through (HVRT) and Low (zero) Voltage Ride Through (LVRT) testing. Requirements for HVRT and LVRT ...

Correctly installing capacitors at the terminals of your motors can lower reactive power requirements and increase system power factor. Induction motors are the primary source of rotary power in the ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what ...

A change to energy market rules promises to make it easier for large-scale renewables and battery storage projects to connect to the grid, by lowering a hurdle put in place in the wake of South ...
