This paper proposes a new control method suitable for active power filters equipped with a smalldc capacitor. The proposed method can achieve not only suppressing the dc capacitor voltagefluctuation in transient states but also compensating all harmonic components in steady states.The proposed method employs a harmonic detection method based on the 7-step compensatorand a repetitive controller with a comprehensive harmonic detection method. The experimentalresults using the active power filter with a small dc capacitor of 300-µF have confirmed that theproposed method has the capability to compensate non-characteristic harmonics produced by a15-kW diode rectifier in steady states without any voltage fluctuations in transient states.
