Abstract

A Paper is proposed based on the DC- Link VSCF AC-DC-AC electrical power system
converter for the aircraft with transport category. This Project presents the Design of D.C link
Converter which can be used for high frequency applications. The D.C link converter, which is
composed of one unidirectional rectifier and one bidirectional inverter, is used to convert variable
input frequency to a constant output frequency of 400Hz in the aircraft generator. Here we are
using 12 Transistors/IGBT as a switching device. IGBT power transistors are used for medium
level power conversion at a faster rate. Proposed method eliminates zero-crossing distortion caused
by the use of diodes. Additionally, the control strategy permits the converter to operate with same
dc-link voltage value required for the conventional six-switch converter. The Simulated and
experimental results are presented. Simulation model can be designed using multisim software.
Contemporary production airplanes already use VSCF as a major source or backup of electrical
power. Prior system had a few problems with the VSCF systems and now the systems are
considered to be safe integrated and replace existing constant-speed hydraulic transmissions
powering CSCF AC generators and utilizing VSCF offers flexibility, redundancy, and reliability.
