ABSTRACT: This
paper proposes a design and implementation of the bi-directional DC-DC converter
for Wind Energy Conversion System. The proposed project consists of boost DC/DC
converter, bi-directional DC/DC converter (BDC), permanent magnet DC generator
and batteries. A DC-DC boost converter is interface with proposed wind system
to step up the initial generator voltage and maintain constant output voltage.
The fluctuation nature of wind makes them unsuitable for standalone operation.
To overcome the drawbacks an energy storage device is used in the proposed
system to compensate the fluctuations and to maintain a smooth and continuous
power flow in all operating modes to load. Bi-directional
DC-DC converter (BDC) is capable of transforming energy between two DC buses.
It can operate as a boost converter which supplies energy to the load when the
wind generator output power is greater than the required load power. It also
operates in buck mode which charges from DC bus when output power is less than
the required load power. The proposed converter reduces the component losses
and increases the performance of the overall system. The complete system is
implemented in MATLAB/SIMULINK and verified with hardware.
