Summary

Sinusoidal current distortion caused by dead time distortion without any distortion correction applied. Test was done on 3 phase servo motor rotating at constant speed.

Graph label says "Torque" but in this case it represents motor phase current in amperes. Lower graph shows PWM duty cycle output from torque/current controller.
