This paper introduce topology of three phase

controlled rectifiers and proposed an accurate Statistical

method to calculate their input current harmonic components,

and calculate THD and harmonic currents with accurate

simulation in various firing angles, then investigate influence

of load variations in terms of firing angle variations on

harmonic currents. Finally a harmonic current database of

rectiûers is obtained in terms of firing angle and load

variations.
