The need to reduce development time of power converters and improve the effectiveness of the test equipment continues to grow. This trend is further accelerated through the development of electricity-based technology, such as the electric or hybrid vehicle. As the price of energy continues to rise, regenerative test equipments used for validating power converters are gaining importance and attention.
The thesis focuses on the development of a regenerative load emulator constituent. This type of intelligent load requires a connection to the network interface, which, for some applications, must be bidirectional and must possess a galvanic isolation. For example, power amplifiers used to emulate the behaviour of a source of alternative voltage, such as a distribution network or an engine, can operate in four quadrants of current-voltage. In such cases, it is important to provide a two-way connection from the network to this type of converter. On the other hand, in the wake of the development of multi-level converters, the isolated feature makes sense for connecting several voltage levels in a random fashion.
The development of such network connexion unit processing AC-DC conversion is treated in this work. The design and optimization of DC-DC and AC-DC converters are treated. A 5kW prototype is used as a base to model, simulate, design and test such a system. Finally, the stability of the interconnection between the two converters is analyzed and tested in real time applications.
