Power injection to AC grid with non-sinusoidal supplies

Harmonic injection is the common problem when d.c. is inverted and fed to a.c. grid using inverters. Harmonic voltages and currents are generated on both d.c. and a.c. sides of the converters in DC/AC transmission systems. The harmonics, if not filtered out, enter the a.c. system and distort the sy...
