For modern navy electric ship, the application of multiple shunt active power filters (SAPF) has become an attractive choice to mitigate the current distortion of the nonlinear loads. Multiple SAPF has the advantage of high power capacity and high reliability. Based on the introduction of SAPF, this paper analyzes the importance of paralleling SAPF in electric ship systems. A new paralleling approach is proposed and compared with several known paralleling/cascading methods. The proposed method separates the tasks of compensating for reactive power and harmonic currents. It has fast response and is suitable for redundancy design. Simulation results verify the analyses.
