“…When compiling a computer model, a classic three-phase three-leg converter control system described, for example, in [37] is used as a basic structure. In order to adapt it to the four-leg scheme, it is necessary to draw up a mathematical description in a natural coordinate system according to a method similar to that used in subsection 2.2, after which the Park transformation is carried out to an orthogonal rotating coordinate system.…”

“…In order to adapt it to the four-leg scheme, it is necessary to draw up a mathematical description in a natural coordinate system according to a method similar to that used in subsection 2.2, after which the Park transformation is carried out to an orthogonal rotating coordinate system. However, unlike [37], where the mathematical model of the three-phase active rectifier is reduced to fa two-phase orthogonal coordinate system, in the investigated case four-leg rectifier model is reduced to a three-phase rotating orthogonal system dq0, where the projection on the 0 axis is not equal to zero. In this case, it is proposed to use, by analogy with [25], an additional independent current circuit with a regulator, the purpose of which is to minimize the 𝑖 0 → 0 current component.…”

A three-phase four-leg bidirectional power converter used as an input stage of an energy storage system using the inductance (L), capacitance (C), and inductance (L) or LCL filter on the grid side is considered. The article provides a variant of the three-phase four-leg bidirectional converter control system implementation based on 3D space vector pulse-width modulation and per-phase voltage control. A brief analysis of the applied control algorithms of the three-phase four-leg bidirectional converter in inverter and rectifier modes is given. A computer model has been built to investigate the operating modes of the converters of the designated class with both balanced and unbalanced load. Studies were carried out by computer modeling methods in order to optimize the parameters of the LCL filter on the grid side with bidirectional energy exchange. Optimal LCL filter parameters and modulation frequencies are determined for the developed converter, providing acceptable quality indicators when operating in bidirectional mode.

“…In other words, a 3-axis coordinate system is constructed to plot the vectors. The Clarke transformation [3,9] is employed to transform a natural three-phase coordinate system into a stationary two-phase reference frame, facilitating the presentation of space vectors in normal setting. To simplify the model, vectors could be represented as bold and undercapitalized character (for example, u, i implies voltage vector and current vector).…”

This paper presents the design and simulation of three phase grid-connected inverter for photovoltaic systems with power ratings up to 5 kW. In this research, the application of Space Vector Pulse Width Modulation (SVPWM) technique for inverter is explored. With the use of SVPWM inverter, synchronization between the inverter and electrical grid follows the Phaselocked Loop (PLL) algorithm. The proposed design is simulated and validated by experimental results.

“…Many control methods have been proposed for inverters [ 6 , 7 ], including linear methods, such as proportional integral (PI) and proportional resonant (PR) controllers [ 8 , 9 , 10 ], and nonlinear methods, such as sliding mode control [ 11 ], direct power control, and hysteresis current control [ 12 ]. Model predictive control (MPC) methods have become some of the most well-known methods [ 13 , 14 , 15 ].…”

Single-phase inverters with an output LC filter, can generate low distortion output voltages, which are suitable for uninterruptible power supply (UPS) systems. The UPS system provides emergency power in the case of utility power failure, requiring high reliability and clean power. The sensorless control method is actually a soft-sensing technique, that reduces system cost, measurement-related losses, and, especially important for UPS systems, enhances the system reliability. This paper proposes a load current sensorless finite control set model predictive control (FCS-MPC) scheme for a single-phase UPS inverter. A time varying observer is proposed, which offers the accurate estimation for individual components simultaneously in periodic load current signal, without subsequent complex calculations. Compared with another two typical sensorless methods (the low-pass filter and the Kalman filter), the proposed observer-based FCS-MPC strategy has smaller load current estimation error and lower output voltage distortion, under both linear and nonlinear loads. The theoretical analysis is verified through simulation and experiment. A single-phase inverter rapid control prototype (RCP) is set up with the Speedgoat real-time target machine, to confirm the effectiveness of the system.
