Abstract :
Permanent magnet Brushless DC motors are
used in several applications because of its advantages
such as high reliability, high power output, constant
torque, low maintenance cost, good heat dissipation and
better efficiency. Also, rapidly decreasing cost of
permanent magnets is an added advantage. Hence,
BLDC motors are suitable for many variable-speed
drive applications. Various DC-DC converters are used
for driving the BLDC motor and Interleaved Boost
converter is one of them. BLDC motor drive is fed
through a diode bridge rectifier which lowers the power
factor. Hence, power factor correction converters are
necessary in such applications. In the present work, to
improve the power quality of the AC mains and hence
the power factor, Interleaved boost converter controlled
by PI controller is used. The gains of the PI controller
are decided by Water cycle algorithm (WCA) using
Integral Time Absolute Error (ITAE) criterion. Speed
control of the BLDC motor is done by controlling the
output voltage of the converter which acts as a DC link
voltage to the Three Phase Voltage Source Inverter
(VSI). MATLAB SIMULINK software is used for the
design and performance analysis of the BLDC.
