Design a filter for harmonics caused by non-linear load and resonance coused by power factor correction capacitor

The traditional approach to power factor correction (PFC) in industrial applications involves installation of power factor correction capacitor banks (PFCC). However, with the expanding use of non-linear equipment such as adjustable speed drives (ASDs), power converters etc., power factor (PF) impro...

Electronics Nuclear engineering The traditional approach to power factor correction (PFC) in industrial applications involves installation of power factor correction capacitor banks (PFCC). However, with the expanding use of non-linear equipment such as adjustable speed drives (ASDs), power converters etc., power factor (PF) improvement has become difficult due to the presence of harmonics generated by the non-linear equipment.
