This paper presents the design and optimization of an isolated DC-DC converter that could be potentially selected for advanced multilevel topologies for offshore wind turbine applications. The superior properties of Silicon Carbide material in terms of switching speed, voltage withstand and efficiency provides the possibility to develop a highly optimized DC-DC converter.
In this paper, a novel bridgeless Flyback power factor correction rectifier is presented. Two active power switches, rather than the line-voltage diode bridge, are used to provide the bidirectional power flow. In comparison with the existing Flyback rectifiers, the proposed topology uses less number of transformer windings which simplifies the complexity of implementation in terms of magnetic utilization...
One of the major drawbacks of Finite Control Set — Model Predictive Control (FCS — MPC), is the high switching frequency, besides a spread harmonic spectrum. Despite of this, the FCS — MPC provides excellent speed to changes of references and disturbances. In this work we present a control strategy based on FCS — MPC that allows a reduction of the switching frequency in steady state, increasing the...
