A prototype model is designed with interleaved dc-dc boost converter for photo voltaic based dc motor speed control. By comparing the carrier signal and the fuzzy logic signals, the motor speed can be modified. Controlling the electrical and mechanical devices is mostly done by fuzzy controller due to the multi input and multi output operation and its performances. Due to the increased switching speed SiC-based applications is more predominant for SiC MOSFETs as compared to Si IGBTs. The proposed system features the dc motor speed control by the varying the duty cycle of the gate signals given to the power devices. Interleaved boost converter is preferred for high voltage gain from the solar panel. Effectiveness of the proposed scheme was checked for various duty cycles with Matlab/Simulink.
