| Abstract |
To avoid a problem of inverter output voltage distortion during zero crossing by the inverter output current a new algorithm of switching control was developed. Special patterns were applied in which nonzero amplitudes of passive vectors are compensated for. The algorithm ensures smooth sinusoidal inverter output current and is suitable for a control system based on speed observer of the induction motor. Multiscalar model of the induction motor and nonlinear feedback were used in the control system. Experimental results are presented. |
