The paper presents a new current control of a PWM shunt active filter with a fuzzy logic estimation of the power devices duty cycles. The innovative control drives well the inverter so the feedback current follows the real one without delay as a deep simulation campaign highlights. The effectiveness of such control has been tested when the distorting load is represented by both a variable speed induction motor drive and a fully controlled a.c/d.c. converter. The fuzzy control proposed shows a very high reduction of the line current harmonic distortion using a medium filter switching frequency.

Abstract
The paper presents a new current control of a PWM shunt active filter with a fuzzy logic estimation of the power devices duty cycles. The innovative control drives well the inverter so the feedback current follows the real one without delay as a deep simulation campaign highlights. The effectiveness of such control has been tested when the distorting load is represented by both a variable speed induction motor drive and a fully controlled a.c/d.c. converter. The fuzzy control proposed shows a very high reduction of the line current harmonic distortion using a medium filter switching frequency.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
