This paper presents experimental and simulation results for two different types of static harmonic compensators for removal of current harmonics from 3-phase supply lines. The comparative advantages and disadvantages of both the schemes are discussed. The first scheme uses sinusoidal signal integrators (SSIs) to extract, amplify and correct particular harmonic current errors in supply lines. Multiple SSIs are required for elimination of harmonic current errors of different orders. The SSI based schemes were reported by many researchers in last couple of decades. The second scheme uses a simplified repetitive controller (RC) to simultaneously remove some dominant current harmonic errors from supply current. Both the schemes have been verified experimentally and by simulation. Emphasis of the present work is to compare the two schemes in respect of performance and controller complexity. © 2022 IEEE.
