One of today's greatest problems are environmental pollution and constant grow of electric energy consumption. In this aspect, important direction is to reduce emissions through the use of green technologies, especially in electric vehicles (EVs). Howewer, the plan for vehicle electrification exacerbates the problem of electricity demand. The current AC grid infrastructure is not very compatible with the integration of RES. At the same time, the low-voltage direct current (LVdc) has a natural application in RES, energy storage systems, EVs etc. The LVdc network can solve the problems of further increasing renewable energy production, vehicle electrification and reducing environmental pollution. Despite the benefits of LVdc concept, its implementation is nearly next to nothing. The main problem is non mature level of power electronics, because DC microgrid has high “saturation” levels of bulky power electronics devices. Secondly, it is a “chicken and egg problem” where there is no evident business model for investors. The potential investors do not see the sizable market and business cases for DC appliances because of the absence of LVdc grids. In this context, the goal of the project is to speed up the energy transition by developing of the advanced power electronics converters that can be considered as a fundamental for future hybrid microgrids. The proposed project is grounded based on several assumptions. One of the main hypotheses is the concept of dual-purpose (or universal) converters to solve “chicken and egg problem”. These devices provide installing the renewable energy generation facilities and storage batteries to the ac grid and reconnecting to the dc grid without power electronics upgrading. Another set of hypotheses concerns the advanced power electronics solutions when new circuits and new approaches in design will help to achieve high power density mature level of dc-ready power electronics converters. Moreover, application of AI will help to optimize design power electronics devices. The main goal of the project will be achieved through a holistic research methodology that combines mathematical methods and knowledge of electrical engineering. The successful implementation of this project will play a very important role for society and the energy system. An important goal of the project is also to initiate long-term strategic research in the field of DC microgrids by creating a strong and sustainable research group
