PENGENDALI KECEPATAN MOTOR INDUKSI 3 FASA DENGAN INVERTER MODULASI LEBAR PULSA SERAGAM BERBASIS FPGA ACEX1K
Abstract: The major
disadvantage of pulse width modulation generating by microcontroller is
that the process completed in a longer
period and slower system response then FPGA based system, while if based on DSP
is its insufficiency in the case of flexibility and reliability. Speed demand
will operate for and performance the reliable controller pushes for the
implementation of evocation of PWM signal at FPGA. This research aim to design
and to implement a device with uniform pulse width modulation based on FPGA Altera
ACEX1K as drive inverter to control the rotational speed of a three phase
induction motor. Design stage of implementing a UPWM signal generating system
started from design entry, compiling, simulation and verification, and hardware
configuration at FPGA Altera acex1k50tc144-3 development system with MAX+Plus II 10.2 Baseline software. At this
research, three phase inverter circuit designed using MOSFET SK727 with DC
input voltage 310 V. Inverter output then loaded with a three phase induction
motor Y2 712-4, 370W/380V, 50Hz model. Result of this research indicate that
the generating of UPWM signal design can be implemented in the form of
hardwared logic at FPGA Altera acex1k50tc144-3 development system, and
applicable to drive inverter as rotational speed controller of a three phase
induction motor. Speed regulating function of this system was implemented by
modulation index and frequency setting. At this research, system have been
tested at setting frequency 10-50 Hz with the variation of modulation index,
and yield a range of range 458-1468 rpm
using Three phase Motor mentioned above.
