Abstract: Half-bridge converters have been widely used in multiple medium power level applications because of the advantages of having less switches and being easy to control. However, their inherent structure leads to low output amplitude and shoot-through problems. In this study, we propose a family of novel half-bridge converters implementing a Y-impedance-network with additional buck-boost voltage adjustment function with the aim of resolving these issues. In order to verify the effectiveness of the proposed topologies, simulations and experiments were conducted, the results which well validate the feasibility of the proposed converters.
