Abstract
Penggunaan motor brushless DC telah banyak digunakan dalam
berbagai bidang seperti peralatan rumah tangga maupun industri
dikarenakan motor ini memiliki struktur yang sederhana, efisiensi dan
torsi yang tinggi, serta menggunakan konsep komutasi elektris yang
berbeda dari motor DC lainnya. Namun pengoperasian pada umumnya
yang menggunakan sumber AC, penyearah serta inverter membuat
tingginya nilai harmonisa arus (THD) sebesar 73,33% dan power factor
sebesar 0,803 dimana nilai ini kurang baik dalam pengaplikasiannya
Pada penelitian ini akan dikaji mengenai proses power factor
correction yang mereduksi harmonisa arus (THD) sumber AC dengan
menggunakan zeta converter dalam pengaplikasian motor brushless DC,
serta pengoperasian motor dengan mengamati respon motor terhadap
kecepatan referensi yang berubah-ubah dan mengamati kestabilan motor
terhadap pembebanan yang bervariasi. Dalam menerapkan metode yang
dilakukan pada penelitian ini, pengoperasian motor brushless DC yang
telah dirancang dapat bekerja dengan baik meliputi respon motor yang
dapat mengikuti kecepatan referensi yang berubah-ubah, serta kestabilan
motor dalam mempertahankan kecepatannya pada pembebanan yang
bervariasi. Proses power factor correction dapat meningkatkan kualitas
daya pada berbagai kecepatan dan mode penerapan yang berbeda-beda,
dimana peningkatan tersebut membuktikan kinerja yang baik dalam
sistem ini dan memiliki nilai kualitas daya yang baik.
========================================================================================================================
Brushless DC motor has been used in several applications such as
home appliances and industry, because of its simple structure, highly
efficient, high torque, and using electric commutation principal which
different to other DC motors. In common application, brushless DC
motors using AC source, rectifier and inverter that occur high current
harmonics (THD) of 73,33% and power factor of 0,803 which these
values are dissatisfactory in application.
In this research, would be discussed about power factor correction
process which reduced current harmonics (THD) at AC source using zeta
converter in brushless DC motor application, as well as motor operation
by observing motor response against reference speed variation and
observing motor stability against load torque variation. By applying the
methods in this research, brushless DC motor operation that has been
designed could work properly, involving motor response that followed the
speed reference and motor stability in maintaining its speed on load torque
variation. Power factor correction process could improve power quality
in speed variation and different mode in this system, which these
improvements show that this system worked properly and has good power
quality.
