Abstract Firstly, the characteristics of marine electric propulsion works, as well as the
actualities of power quality of marine electric propulsion system are introduced, and the significance of
improving power quality of marine electric propulsion works is discussed. Afterwards, the
power quality improving methods applied to marine electric propulsion works nowadays are
analyzed. Finally, a new approach - the /APF/PF Circuits (Combination of Active Power Factor
Compensator and Series Active Filter aided by parallel Passive Filter) -is proposed for power factor
correction and harmonic suppression of marine electric propulsion works. According to the
simulation experimental results, it shows that the solution suggested in this paper seems to be promising
pensate for harmonics and to promote power factor in marine electric propulsion works.
