Abstract
Electric power is of increasing importance in aeronautical systems. As a consequence,
static converters have become widespread, and power electronics is crucial for improving
performance, reliability and competitiveness.
The aim of this thesis is to contribute to the design of electrical networks by using
modular generic converters. To determine their structure, an inventory of power electronics
applications is carried out in the framework of a "more electric" aircraft.
The modularity of these power conversion blocks opens the way for power
segmentation and redundancy, that enables systems availability to increase. Following this
approach, several fault-tolerant inverter topologies are compared, both analytically and by
simulation based on the physical model of a flight surface electrohydrostatic actuator.
For the experimental studies, power electronics modules are designed to operate a
reconfigurable inverter that is dedicated to a permanent magnet synchronous motor drive.
Connected to the neutral point of the wye-connected motor, this inverter has a fourth leg that
acts as a mutualised redundancy.
Lastly, to extend the power electronics generic module’s field of application, three
AC/DC converter topologies are proposed in order to improve power management, in
comparison with conventional topologies, with respect to electrical and thermal design
criteria.
