“…FPGAs have been employed for implementing diverse control schemes of multilevel converters ( [11][12][13][14][15][16][17][18][19][20][21]), and also for implementing motor-drive controllers ( [17][18][19][20][21][22][23][24][25][26]). References [17][18][19][20][21] propose FPGA-based controllers for multilevel converters operating as motor drives, as it is proposed here. However, [17][18][19][20][21] do not explain the FPGA controller structure, do not discuss the design methodology to obtain an efficient implementation, and generally do not deal with the voltage balancing problem.…”

This paper proposes a closed-loop control implementation fully-embedded into an FPGA for a permanent-magnet synchronous motor (PMSM) drive based on a four-level active-clamped converter. The proposed FPGA controller comprises a field-oriented control to drive the PMSM, a DC-link voltage balancing closed-loop control (VBC), and a virtual-vector-based modulator for a four-level active-clamped converter. The VBC and the modulator operate in consonance to preserve the DC-link capacitor voltages balanced. The FPGA design methodology is carefully described and the main aspects to achieve an optimal FPGA implementation using low resources are discussed. Experimental results under different operating conditions are presented to demonstrate the good performance and the feasibility of the proposed controller for motor-drive applications.

“…Generally, there are three most important types of topologies for modern multilevel inverters, which are applied in the industry, and these topologies are a flying capacitor multilevel inverter (FC‐MLI), diode‐clamped multilevel inverter (DC‐MLI), and cascade H‐bridge multilevel inverter (CHB‐MLI) [3–6]. Furthermore, the flying capacitor multilevel inverter (FC‐MLI) and diode‐clamped multilevel inverter (DC‐MLI) are suitable for medium‐voltage/high‐power applications.…”

“…Additionally, their semiconductors can be controlled at low frequency, minimising the propagation of highfrequency components. Common topologies of multilevel inverters are diode clamped [13,14], flying capacitor [15,16] and cascaded H-bridge (CHB) [17,18], each one with its feature and validity. The CHB is a potential candidate for BSS applications applied to medium-voltage grids.…”

A distributed generator (DG) based on renewable energy is a promising technology for the future of the electrical sector. DGs may benefit utility companies and customers in a variety of perspectives. However, DGs suffer from intermittent behaviour. Storage systems appear as an attractive solution to support the continuous operation of DGs. The technology within the storage also plays an important role, since DGs and storage are connected in medium-voltage grids. The use of batteries and the DC/AC converter in its conventional structure presents drawbacks in such grids. In this context, this study presents a three-phase transformerless battery storage system (BSS) based on a cascaded H-bridge inverter applied to a medium-voltage grid. The BSS is composed of eight equal series connected H-bridge converters, without bulk transformers, for connection to a distribution grid. Each converter contains 75, 12 V/600 Ah lead-acid batteries. The converters are controlled through pulse-width modulation at 600 Hz. The BSS is able to keep working even with a failure of one of its converters. Reactive energy compensation not compensated by an existent passive filter is also performed. A case study with simulated and experimental results obtained through a hardware-in-the-loop system is presented showing the efficacy of the proposed BSS.
