| Abstract |
Unlike traditional passive filters, modern active
filters have the following multiple functions; harmonic filtering,
damping, isolation and termination, reactive-power control for
power factor correction and voltage regulation, load balancing,
voltage-flicker reduction, and/or their combinations. Significant
cost reductions in both power semiconductor devices and signalprocessing
devices have inspired manufactures to put active filters
on the market. This paper deals with general pure active filters
for power conditioning, and specific hybrid active filters for
harmonic filtering of three-phase diode rectifiers. |
