Abstract

Based upon the conducted experiments the dependence of 5-th, 7-th and 11-th harmonics of the current consumed from mains by AC adjustable speed drive with voltage inverter and voltage forming using PWM from the load value is set. The results of regressiveanalysis are presented as functions of the investigated dependenses.
