Abstract

Seiring dengan perkembangan zaman pengaplikasian dari energi terbarukan semakin banyak digunakan salah satunya pada bidang transportasi. Banyak dijumpai alat transportasi yang menggunakan motor modern seperti switch reluctance motor dan brushless DC (Direct Current) motor. Motor BLDC atau motor brushless DCmemiliki rugi-rugi mekanik yang rendah karena tidak menggunakan sikat (brush) seperti motor dc konvensional. Karena pada mtor brushless dc menggunaan magnet permanen maka diperlukansensor untuk mengetahi back-emf, selain dari pada itu untuk pengaturan switchingpada motor BLDC menggunakan inverter tiga fasa. Dalam pengaturan tegangan output pada inverter tiga fasa akan menghasilkan sinyal keluaran Pulse Width Modulation(PWM) yang akan membentuk komutasi 120°. Arus eksitasi motor brushless dc yang dikontrol secara elektronik berdasarkan umpan balik posisi dapat menghasilkan torsi bebas riak, namun jika motor brushless dc. Maka dari itu tugas akhir ini akan membahas tentang desain dari inverter tiga fasa untuk motor BLDC menggunakan metode six-step commutationdengan ripple suppression hingga pembuatan prototipe dengan menggunakan bahan yang tersedia dalam negeri.

Along with the times, the application of renewable energy is increasingly being used, one of which is in the transportation sector. There are many means of transportation that use modern motors such as switch reluctance motors and brushless DC (Direct Current) motors. BLDC motors or brushless DC motors have low mechanical losses because they do not use brushes like conventional dc motors. Because the brushless dc motor uses permanent magnets, a sensor is needed to determine the back-emf, apart from that for switching settings on BLDC motors using a three-phase inverter. In setting the output voltage on the three-phase inverter, it will produce a Pulse Width Modulation (PWM) output signal which will form 120° commutation. The excitation current of a brushless dc motor which is controlled electronically based on position feedback can produce ripple-free torque, however, if the motor is brushless dc.Therefore, this final project will discuss the design of a three-phase inverter for BLDC motors using the six-step commutation method with ripple suppression to making prototypes using locally available materials.
