Abstract
Keuntungan seperti efisiensi tinggi, rasio inersia/torsi tinggi, jangkauan pengaturan kecepatan yang besar dan rendahnya electro-magnetic interference (EMI) menjadi alasan motor brushless DC (BLDC) menjadi pilihan yang tepat dalam banyak aplikasi dikehidupan sehari-hari seperti pada peralatan rumah tangga, industri dan kesehatan. Motor BLDC terdiri dari belitan 3 fasa pada stator dan magnet permanen pada rotornya. Sebuah voltage source inverter (VSI) digunakan untuk meciptakan komutasi elektris yang didasarkan pada posisi rotor. Komponen inverter pada VSI menyebabkan tingginya THD (Total Harmonic Distortion) yang berpengaruh pada buruknya nilai PF (Power Factor). Pada tugas akhir ini akan dilakukan penelitian mengenai penggunaan Bridgeless Isolated-Cuk Converter untuk mengurangi efek buruk harmonisa terhadap power factor. Bridgeless Isolated-Cuk Converter dipilih karena dapat dioperasikan dalam berbagai jangkauan kontrol kecepatan serta torsi beban selain itu juga dapat digunakan untuk memperbaiki faktor daya dari 0.171 menjadi 0.999753.
==========================================================================
Advantages such as high efficiency, high ratio inertia/torque,
wide range of speed control and low electro
-
magnetic interference (EMI)
are the reasons for brushless DC motors (BLDC) to be the right choice in
many daily life applications such as household a
ppliances, industry and
medical equipment. The BLDC motor consists of three phase windings
on the stator and a permanent magnet on the rotor. A voltage source
inverter (VSI) is used to create electrical commutations based on the rotor
position. The inverte
r component of VSI causes high THD (Total
Harmonic Distortion) which affects the poor value of PF (Power Factor).
In this final project will be conducted research on the ability of Bridgeless
Isolated
-
Cuk Converter to reduce the side effect of harmonics on
power factor. Bridgeless Isolated-Cuk Converter is chosen because it can be operated in various range of speed control and also voltage source can also be used to improve power factor from 0.171 to 0.999753.
