Steady State Characteristics of a Novel Shunt Hybrid Active Power Filter Adopting the Combined Control Approach

This paper proposes a combined control approach for a novel shunt hybrid active power filter and describes the steady state characteristics of this device on the basis of its control method and operation princi-ples.The steady state characteristic curves are obtained.The relationship between the steady state performance and control gain is well discussed.And its suppressing action upon the possible resonance in the circuit is ana-lyzed in detail.Computer simulation and experimental results showed that the single-phase hybrid type series active power filter has good steady state compensation characteristics and can dramatically suppress parallel resonance and series resonance between source impedance and shunt passive filter.
