Research on Predictive Direct Power Control of Three-phase Separated Hybrid Power Electronic Transformer

In recent years, power electronic transformers (l'EF) that can convert electrical energy have been a research hotspot. In order to better adapt to the requirements of smart grids and high-power applications, a hybrid power electronic transformer (IIPET) and its control method are proposed. Firstly, a mathematical model based on the topology of the hybrid power electronic transformer is established. Then a predictive direct power control strategy is designed according to the expected goal. Finally, simulation in NIATIAB/Simulink verifies the effectiveness of the proposed control strategy.
