“…Outras topologias mais complexas podem ser empregadas, introduzindo o conceito de inversores multiníveis, que trabalham com mais de dois níveis de tensão de saída. O mais popular é o conversos multinível com ponto de neutro grampeado (NPC -"neutral point clamped"), o de capacitor flutuante (FC -"the flying capacitor") e o cascata em ponte H (CHB -"cascaded H-bridge") como pode ser visto na Figura 4.4 (DE OLIVEIRA et al, 2020;CAMARGO;ENCARNAÇÃO, 2020;RODRÍGUEZ et al, 2009).

“…That is, considering Regarding the number of capacitors necessary to produce the appropriate DC-link ripple values, the CHB-SDC structure, besides presenting a smaller number of capacitors than single-phase structures, presents total capacitance values, on average, six times lower than the classical CHB topology [27,[32][33][34][35]. Some studies claim that these values can be up to 10 times lower [28,[36][37][38], demonstrating evident superiority of three-phase structures over single-phase structures in terms of the total capacitance.…”

“…This characteristic is essential for building a three-phase sinusoidal wave with low total harmonic distortion (THD), a fundamental condition for the use of the CHB-SDC in several power electronics equipment, as the STATCOM mentioned above. Thus, with the graph theory applied to this five-level converter, a computer algorithm was developed, capable of gathering each one of the 4096 possible paths and mapping the converter's unipolar switching states [9,11,17,38]. However only 640 states are useful for equipment operation, that is, these combinations do not generate short-circuit states.…”

A Novel Cascaded Multilevel Converter Topology Based on Three-Phase Cells—CHB-SDC

This paper proposes a new cascaded multilevel converter topology based on three-phase H bridge cells with a common DC-link structure. The proposed multilevel converter topology main advantages, compared with literature renowned multilevel converters topologies, are discussed in the paper, such as modularity, construction, implementation cost, and DC voltage ripple mitigation. Despite presenting an elementary structure and easy implementation, the use of classic PWM switching strategies is not feasible for this topology, causing the appearance of several short-circuit states between its capacitors. Thus, a graph theory algorithm combined with a model predictive control is also proposed in this work to identify and avoid the new cascaded multilevel converter short-circuit switching states and, concomitantly, guaranteeing the converter output power quality. In order to validate the presented topology applicability, a low voltage synchronous static compensators (STATCOM) with an optimal switching vector model predictive control (OSV-MPC) is implemented in a hardware-in-the-loop platform. The real-time experimental results prove the proposed multilevel topology and the OSV-MPC control strategy effectiveness.

“…The general recommendations for the design of the control system are given in the works, the criteria of stability and the minimum necessary phase conditions for the torque control are indicated, the results of the experimental study of a typical induction motor are presented. In [8], a method of predicted current control with field orientation was described, which was developed for a three-level inverter with a fixed neutral point for controlling a three-phase induction motor. The algorithm for calculating the optimal switching vector was used in the method, the control circuit of the stator voltage, stator current and motor's rotor speed was determined.…”

“…The methods presented in [7][8][9][10][11], built on the basis of complex algorithms of neural networks and fuzzy logic, allow to effectively control the parameters of electric machines, however, at the same time, they have certain disadvantages: high complexity of algorithms, a large number of controlled parameters, high design load and the need for a full-fledged system model [12,13].…”

Goal. Development of a mathematical model of indirect field-oriented control of a twin-screw electromechanical hydrolyzer. Methodology. The paper presents a mathematical model of Indirect field-oriented control of twin-screw electromechanical hydrolyzer. The mathematical model was developed in the MATLAB / Simulink software environment. The determination of the main parameters of a twin-screw electromechanical hydrolyzer was carried out by developing a finite element model in the Comsol Multiphysics software environment. Results. Based on the results of a mathematical study, graphical dependences of the distribution of magnetic induction in the air gap of a ferromagnetic rotor, a spatial representation of the distribution of magnetic induction on a 3D model of a ferromagnetic rotor of a twin-screw electromechanical hydrolyzer were obtained. The results of finite element modeling were confirmed by a practical study of a mock-up of a ferromagnetic rotor of a twin-screw electromechanical hydrolyzer. By implementing the MATLAB / Simulink model, graphical dependences of the parameters of the ferromagnetic rotor of a twin-screw electromechanical hydrolyzer are obtained under the condition of a stepwise change in the torque and a cyclic change in the angular velocity. Originality. The paper presents an implementation of the method of indirect field-oriented control for controlling the ferromagnetic rotor of a twin-screw electromechanical hydrolyzer. The work takes into account the complex design of the ferromagnetic rotor of a twin-screw electromechanical hydrolyzer. Practical significance. The practical implementation of the results of mathematical modeling makes it possible to achieve effective control of a complex electromechanical system, allows further research to maintain the necessary parameters of the technological process and to develop more complex intelligent control systems in the future.
