摘要：The paper presents the impact of phase failure work on power converters.The study includes a three-level NPC inverter (Neutral Point Clamped),controlled by Voltage Oriented Control (VOC).The NPC converter integrates renewable energy sources with the power grid.The article includes a discussion about the causes of phase failure work and an analysis of the converter’s failure and its impact on the power grid.The simulations were performed in MATLAB/Simulink.The study also includes the concept of an integrated protection for IGBTs,controlled by the DSP microprocessor system.
