| Abstract |
The design of synchronous multiphase DC-DC
converters allows improvements of the characteristics of high
power systems. The automotive industry forecast that future
power demands inside a car will oscillate between 2.5 kW
and 3.5kW, keeping a dual system of 42/14V batteries. In
this paper, an optimal fuzzy controller has been developed
to control a synchronous multiphase converter of 1.6kW for
dual voltage architecture or in hybrid vehicle applications.
The proposed optimal fuzzy controller is analyzed and
simulated together with a non lineal model of the power
stage, by means of Matlab and Simulink. This simulation
platform also integrates tools for a future implementation of
the controller embedded in a FPGA. The main contribution
of this work is the implementation of an optimal fuzzy
algorithm of control that can be used independently of the
number of phases of the converter, making it suitable to
be applied in a wide range of high power applications.
This controller has been designed having in mind the goal
of developing a real-time FPGA-based controller, so the
complexity has been reduced to a minimum. Hybrid vehicles,
aerospace and naval industry power systems can also benefit
from the development of this algorithm. |
