This paper presents a new shunt Active Power Filter (APF) based on Stacked Multicell (SM) converter topology. The main properties of SM converter, which causes increase in the number of output voltage levels, are transformer-less operation, natural selfbalancing of flying capacitors voltage and lower power rating and number of components compared with other conventional multilevel converters. Furthermore, in this paper a new control method based on instantaneous reactive power (IRP) theory (P-Q theory) and Predictive Current Control using modified phase shifted sinusoidal PWM modulation method has been presented and applied to proposed APF. The proposed APF is simulated using PSCAD/EMTDC software and simulation results are presented to validate the effectiveness and advantages of the new proposed configuration of APF.
