This paper presents a topology of single-phase AC-DC converter for application in Solid State Transformer (TES), called ND1, resulting from the combination of two three-level NPC (Neutral Point Clamped) arms and having characteristics of a DAB converter (Dual Active Bridge). Has been used to drive electric motors with high power density, wind power, locomotive traction and other applications where weight and vo...
The converters CA-CC are a most used converters in industry and be present in practically all electronic devices, illumination systems, laptops, biomedical equipment and others. However, this converter behaves as nonlinear load to electric system and producing a non-linear current and have high value of Total Harmonic Distortion (THD). To around this issue, the Power Factor Correction (PFC) is made using dedica...
This work deals with the study of a three-level inverter with Neutral Point Clamped (NPC), proposed for the interconnection of energy conversion systems to the grid. In order to accomplish a complete study an inductive L is proposed and, vector control techniques, and PLL technology as synchronization method are used. Equations are developed for the determination of the losses of the converter, which can be app...
