- This master's thesis investigates the problem of voltage unbalance, its consequences and its potential solutions in the context of bipolar DC microgrid. To address those questions, a state of the art is conducted to give a comprehensive overview of all existing solutions in the literature. Then, three devices are chosen based on suggested criteria, thoroughly designed and validated on small testbenches. Subsequently, simulations are conducted on a bigger testbench that represents better real-life scenarios. From the results of those simulations, it is concluded that the studied solutions provide good balancing capabilities and can maintain a bipolar DC microgrid stable. From those results, this work opens a discussion about the possible locations of those balancing devices within a grid. Finally, this thesis gives insight on the current state of standardization for bipolar DC electrical network.
