Different harmonic reduction Technique

1.4 Different harmonic reduction Technique.

Many harmonic reduction methods exist. These techniques based on passive components, mixing single and three-phase diode rectifiers, and power electronics techniques as: multi-pulse rectifiers, active filters and PWM rectifiers (Fig. 1.1). They can be generally divided as:

A) harmonic reduction of already installed non-linear load;

B) harmonic reduction through linear power electronics installation.
