Single source boost converter fed drives may not be able to power continuously motor drive. Since PV power is not available at all times, one or more sources are proposed to reduce the effect of this condition. This paper presents a hybrid photovoltaic and permanent magnet synchronous generator (PMSG) wind-based multi-port dc-dc converter for a direct torque control (DTC) based induction motor drive. The proposed converter for PMSG wind ensures power factor correction to eliminate reactive power of the system, which improves the system's power quality. Further, the proposed drive shows lesser harmonics in the output, verified by measuring total harmonics distortion of drive current, THD is less in the range of 2%. Since more than one source is used to propose a multi-port converter that continuously supplies reliable power to a four-switch three-phase inverter. Then the hysteresis control also utilized to reduce the total harmonic distortion (THD %) values. The proposed multi-port converter-based four-switch three-phase inverter drive is simulated in MATLAB/Simulink environment. Results are presented to verify the merits of the proposed motor drive.
