Harmonic mitigation deals with the mitigation of voltage harmonics generated by inverters within the range prescribed by various grid codes, as defined in and shown in Table 1. The angles in the solution of the transcendental expressions are such fetched that the low order harmonics are below the threshold prescribed for each harmonic.
Selective harmonic and mitigation techniques have shown promising scope in controlling the low order harmonics and integrate the power conversion-based systems in an effective manner.
Selective harmonic elimination and mitigation (SHE and SHM) are well-known effective techniques to control the low-order harmonics in the voltage and current waveforms generated by DC–AC converters, which otherwise pollute the grid waveforms and lead to undesired losses.
There is a better approach, and that is to break the filter package from the drive/rectifier supplier or electrification packager, create your own filter design and specification, and bid it out to vendors who specialize in harmonic filter design and manufacturing.
Methods of harmonic compensation: (a) controller based HC , , and (b) power line HC , . In the second method, the harmonics are injected into the power line to negate the current harmonics generated at the PCC, alongwith regulating the injected power.
The PFC and harmonics elimination is well achieved since source currents is sinusoidal and in phase with the source voltage. As shown in Fig. 9, the DC voltage is well regulated to 170 V with negligible voltage ripple. This paper considers the control design for a SAPF which reduces harmonics and provides PFC.

It can be seen from Figure 2 that the impedance of the capacitor branch will be small at high-frequencies, allowing a large AC current to flow through this branch.
