Escuela de IngenieríaMulti-port power converters have a very important role today because they are used used in electromobility applications and hybrid energy storage systems (HESS). However, their optimal operation requires advanced control techniques due to the handling of multiple variables simultaneously. This thesis presents the development of an Optimal Switching Sequence (OSS) model predictive control (MPC) method applied to a three-port converter (TPC), which has been connected to an anisotropic permanent magnet synchronous machine (PMSM) and two dc voltage sources (VS). Based on a review of TPCs, classical control methods and MPC methods, the converter used with its mathematical formulation is presented. Then, theoretical principles of vector modulation and the machine for the design of the current controller are presented. The latter is based on two steps, the first one uses the dynamic model of the machine to find the optimal seven-segment witching sequence (7S-SS) that reduces the value of an objective function without using weighting factors and the second one uses the redundant vectors (zero vectors) optimally distributed to control the current in another of the ports.The results validate the method by experimental and simulation tests. The strategy presents a defined harmonic distortion, without sacrificing the dynamic response. In addi tion, an implementation with asymmetric modulation reduces the tracking error by 65.36% and a delay compensation reduces it by 92%. Furthermore, the new strategy manages to reduce the optimization problems to be solved by the steady-state algorithm from 6 to 1. Thus, the proposed control becomes attractive for implementation in real hybrid sys tems, which impose challenges of durability, versatility and reliability to the electrical system.

- ItemDesign, Analysis and Experimental Verification of Arm Link Enhanced Modular Multilevel Converter(2024) Aguilar Villaseca, Rodrigo Ignacio; Tarisciotti, L.; Pereda Torres, JavierThe Modular Multilevel Converter has gained attention in high- and medium-voltage DC-AC conversion due to its modularity, scalability, and excellent results in power quality and efficiency. However, its complexity, multiple control loops, and extensive measurements make it unsuitable for low-voltage applications. Additionally, the power ripple in sub-modules, poses challenges in low-voltage scenarios. To overcome the disadvantages of the MMC at low voltage and operate it from zero frequency to high output frequency, the Arm Link Enhanced Modular Multilevel Converter (ALE-MMC) was proposed, which employs dual active bridges to transfer power ripple between the upper and lower submodules, substantially reducing its capacitance and eliminating all voltage measurements from the submodules. This work analyzes and test the ALE-MMC in the entire operating range, giving design insights, and highlighting the various benefits the proposed topology can obtain in low voltage drives applications in terms of circulating currents control, Dual Active Bridge requirements and efficiency. Simulation results are presented in a three-phase converter to verify its operation at high power, and experimental results of a low-scale single-phase prototype are used to assess the operation under different scenarios.
