Modeling and Simulation of Permanent Magnet Machines Output Voltage Conditioning in the Air Three Generator

Abstract:

The main role of the permanent magnet machine in the aviation frequency alternator is as the exciter. Its main function is not only to supply power for the generator controller but also supply the excitation current to exciter by supplying field winding of exciter with DC excitation voltage in the case without the emergency power. So we have to rectify 115V AC of permanent magnet machine output and make DC/DC conversion, so that the output is the suitable DC voltage. In the actual, it is very troublesome to make parameter tuning to rectifier module and DC/DC module, so this it is necessary to make model and simulation research. In this paper, we make module, simulation and parameter tuning for the rectifier and DC/DC transformation module in the MATLAB environment. From the simulation results, we can get that the model is correct, the parameters are appropriate.
