Voltage Regulation of Permanent Magnet Synchronous Generator in Variable Load by Using Buck-Converter in Aircraft Applications

Abstract

Generator drive applications have been used in many different systems for a long time. There are plenty of different kinds of generators and generator control topologies. One of the generator control topologies is the DC-DC buck converter. So implementing a buck converter topology to generator control makes the design simple efficient and easy to apply. This paper presents a control application of a 15kW permanent magnet synchronous generator by using a buck converter in aircraft applications. This application involves new technologies such as Silicon Carbide and environmentally reliable components. According to the theoretical calculations the selected components for practical implementation are given. The losses of selected semiconductors and passive components are calculated individually. At the end of the paper the theoretical calculation and simulation results are compared with the experimental results.
