The paper suggests Selective Harmonic Mitigation problem formulation as a time domain constrained optimization Total Harmonic Distortion minimization with selected mitigated harmonic magnitude inequality constraints. The results of optimization are presented in the form of dimensionless criterion that allows to trade-off more grid current for less coupling inductance (or vice versa). Though an elementary two-level three-phase inverter is considered, the general approach is applicable to different multilevel inverters and modulation strategies.
