This paper presents the direct torque-controlled induction motor drives (DTCIMDs) based on a retrofit 44-pulse rectifier (44PR). A 22-phase polygon autotransformer (PA) is designed to supply rectifiers. The above structure improves power quality standards in grid and complies with requirements of IEEE-519 standard for different loads. Besides, factor close one obtained wide range DTCIMD perform...

This paper presents a comprehensive analysis of various bipolar Multicarrier Pulse Width Modulation (MCPWM) strategies with Sinusoidal reference for three phase Nine level Trinary Source cascaded inverter. A new approach of nine levels is for medium voltage applications. The proposed topology uses reduced number of switching devices and thus reducing losses and low THD in comparison with the co...

This research explored the independent solar power system (ISPS), including maximum point tracking (MPPT) technology and DC (direct current) to AC (alternating full-bridge inverter (FBI) control technology. study combined perturb observe (P&O) algorithm based on output voltage strategy proposed optimized FBI ISPS. The variable frequency duty cycle (VFVDC) had adjustable cycle. VFVDC was compare...
