The master's thesis comprises analysing, designing, and constructing a transistor leg with an integrated coupled inductor. The work aimed to check whether there is a topology of the transistor leg that would tolerate both transistors' partial simultaneous conduction.
The transition between a simple transistor leg generally used in switching converters towards the proposed solution was carried on using the LTspice program simulation tool. The proposed topology allows the simultaneous conduction of both transistors in pairs and also proves superior circuit robustness. In the event of a failure of one of the transistors, it protects the other transistor from destruction, as the overcurrent protection has a broader time window to react.
The proposed topology with an integrated coupled inductor demonstrates high efficiency compared to a conventional switching converter.
