- This paper describes a possibility of the new, non-linear current controller usage. This current controller was compared with delta modulation controller. By the predictive current controller usage the current shape quality was improved. The THD(I) coefficient of the output current was reduced about 30%. The average magnitude of the current error vector was decreased about 40%. It causes less power losses and less torque fluctuations of induction machine. Simultaneously with THD(I) decrease, the reduction of transistors switching number was achieved. The switching frequency of DC/AC inverter was reduced about 94% at low motor speed range in comparison to delta modulation controller use. It means the inverter efficiency improvement. The predictive controller has not disadvantage of delta modulation controller called as average current error. The new current controller keep extremely good dynamics in transient state comparable to delta modulation controller. It was shown on experimental research. The new, non-linear current controller and control system of DC/AC inverter was realized by microprocessor system usage. It ensure good dynamics of torque forming and better efficiency of combined, inverter-motor system.
