“…Additionally, the CHB-based MMC design avoids the need to incorporate an extensive array of flying capacitors or clamping diodes in the power converter topology [17]. Consequently, one of the most widely discussed topologies in the literature is the seven-level voltage source converter (7L-VSC) based on three CHB cells in series per phase [18]. However, both 2L-VSC and 7L-VSC topologies are based on AC-DC-AC configurations, which require the inclusion of an intermediate stage of energy storage elements such as capacitor banks.…”

Power converter technologies have become vital in various applications due to their efficient management of electrical energy. With the growing prominence of renewable energy sources such as solar and wind, the high penetration of power electronic converters has been justified. However, ensuring power quality has emerged as a significant challenge for grid-connected power converters. The divergence from the ideal sinusoidal waveform in terms of magnitude and frequency impacts both grid-side currents and voltages. Several studies have proposed solutions to address power quality issues at the load side. The advancement of power converters has been fueled by the development of high-performance microprocessors and the emergence of high-speed switching devices, such as SiC-MOSFETs. This paper focuses on the design of voltage source converters, particularly those based on SiC-MOSFET semiconductor devices. The article presents the design of H-Bridge cells, discusses two-level voltage source converters based on cascade H-Bridge cells in a parallel configuration with experimental fault analysis, addresses the seven-level voltage source converter topology, and explores the design and experimental results of the matrix converter. The findings underscore the importance of considering the entire converter design for improved performance at high switching frequencies. The article concludes by summarizing the main outcomes and implications of this research.

Power converter technology has expanded into a wide range of low, medium, and high power applications due to the ability to manage electrical energy efficiently. In this regard, the modular multilevel converter has become a viable alternative to ensure an optimal harmonic profile with a sinusoidal voltage at the load side. Model predictive control (MPC) is a state-of-the-art technique that has been successfully used to control power electronic converters due to its ability to handle multiple control objectives. Nevertheless, in the classical MPC approach, the optimal vector is applied during the whole sampling period producing an output voltage. This solution causes an unbalanced switching frequency of the power semiconductor, which then causes unbalanced stress on the power devices. Modulation strategies have been combined with MPC to overcome these shortcomings. This paper introduces the experimental assessment of a 7-level converter combining a simple phase shift multicarrier pulse-width modulation approach with the MPC technique. A custom test-bed based on SiC-MOSFETs switches is used to validate the proposal.

“…These algorithms need a large number of measured signals which are necessary for computing of proper control steps [1]. For example, in case of STATCOM application these algorithms must ensure balancing of dc-link capacitors voltages and generating of suitable current waveform into the power grid [2], [9]. For optimal function of the control algorithm, all dc-link voltages, all compensation currents, all grid voltages and all grid currents have to be measured.…”

A new universal multi H-bridge converter is introduced in this paper. The main purpose of proposed universal converter is simple testing of modular multilevel topologies as CHB and M2LC topology. The whole converter is designed to fit a standard 2U height 19" rack mount enclosure. The converter consists of four 5 kW power cards with H-bridge IGBT modules. There are front and back panels in the converter construction dedicated to connecting a control unit, necessary quantities signaling, and enabling different and modular topology configurations using power terminals interconnection. The converter is also equipped with inevitable protections and measurements.
