Abstract

This paper investigates PWM method for the dual-inverter fed open end winding three-phase induction motor drives. This is aimed to improve the quality of the output voltage as well as to enhance the motor performance by solving the drawback of the PWM method. The proposed PWM method operates two inverters in different technique, i.e one inverter operates in square wave mode (slow switching) and one inverter in PWM mode (fast switching). Although the PWM method can improve the quality of the inverter output voltage over the two-level inverter output, the proposed PWM method causes an excessive ripple in both torque and stator current especially at the transient period. The drawback is solved by applying a new switching strategy that manage the inverter switches operate in turn between slow switching and fast switching in one circle of operation. The proposed method is verified via simulation. The result shows that the quality of output voltages improves for all modulation indices in comparison with two-level inverter. Furthermore, torque ripple is reduced, and current ripple are improved as the current waveform is enhanced to be more symmetrical.

Abstract

This study aims to develop an electric vehicle conversion kit module as a vocational learning tool at SMK Muhammadiyah 1 Surakarta. The research method used is Research and Development (R&D), which includes the design, production, and trial phases of the module. Evaluation was conducted through concept comprehension tests and practical skill assessments before and after using the module. The results indicate that the electric vehicle conversion kit module significantly enhances students' understanding and skills related to Electric Motorized Vehicles (KBL) technology. Furthermore, the study's findings were published in a national ISSN journal and mass media. As an additional output, a copyright for the module was obtained, demonstrating its innovative contribution to vocational education and electric vehicle technology.
