Abstract: The non-linear load such as single-phase diode rectifier, inverters/converters, low voltage power supplies, SMPS and personal computers are exists in every industry. In all three-phase system the lowest and significant order of harmonic will be 5th harmonic after the fundamental. This harmonics increases losses in the form of heat dissipation and also contributes to eddy currents and core losses. Due to this effect, the power quality gets affected. In this paper a brief survey of harmonic mitigation techniques are presented which are used to mitigate power quality problems.
