“…Finally, the presence of the anti-parallel diodes in the VSI and their absence in the CSI reflects the fact that the CSI needs power switches that can block reverse voltages, unlike the VSI. Fortunately, WBG power switches offer some interesting possibilities for realizing reverse-blocking switches that are not easily achieved with silicon-based IGBTs or MOSFETs [54]- [56]. Unfortunately, space in this paper does not permit a full discussion of the potential advantages offered by the CSI inverter topology over the VSI when WBG power switches are introduced.…”

“…However, this number is in fact similar to that of industry-approved two-stage and quasi-single-stage solutions. Moreover, a new impulse for industrialization can be given by the recent developments in monolithic reverse-blocking and bidirectional semiconductor devices that have been reported for Si, SiC and GaN technologies [137][138][139][140][141][142]. This technology can make the isolated matrix inverters attractive to the industry by reducing the number of discrete devices by up to twofold at the AC side.…”

This paper presents a review of isolated matrix inverters. The study contributes to creating a point of reference for a comprehensive classification of existing solutions. Over 30 topologies were reviewed, and the main advantages and disadvantages discussed. Applications of isolated matrix inverters are summarized in a tabular form to demonstrate their flexibility for different power and voltage levels achieved due to the presence of a transformer. These inverters have been proposed for the uninterruptible power supplies, high and low-voltage/power photovoltaic systems, low-power fuel cell, different low- and high-voltage battery and/or electric vehicle chargers, audio amplifiers. The fully controlled switches on both terminals of these converters typically can provide the bidirectional power transfer capability, which is also addressed for most of the topologies, but requires some modification in their modulation strategy. Average efficiency of today’s isolated matrix inverters is comparable with the two-stage power converters; however, they can provide higher reliability and lower cost.

“…This bidirectional switch could be formed either by two conventional IGBTs in common-emitter or by a common-collector and reverse blocking IGBT connection. Actually, a classical IGBT semiconductor structure could be replaced by a reverse blocking MOSFETs for a high-voltage [21] and high-switching frequency operation [22]. Although more than two cells in a series connection are conceptually feasible, for the sake of simplicity, two-cell 3L-TNPC converters have been introduced as a proof-of-concept applied to conventional string rooftop PV applications.…”

Multilevel converters are widely considered to be the most suitable configurations for renewable energy sources. Their high-power quality, efficiency and performance make them interesting for PV applications. In low-power applications such as rooftop grid-connected PV systems, power converters with high efficiency and reliability are required. For this reason, multilevel converters based on parallel and cascaded configurations have been proposed and commercialized in the industry. Motivated by the features of multilevel converters based on cascaded configurations, this work presents the modulation and control of a rooftop single-phase grid-connected photovoltaic multilevel system. The configuration has a symmetrical cascade connection of two three-level T-type neutral point clamped power legs, which creates a five-level converter with two independent string connections. The proposed topology merges the benefits of multi-string PV and symmetrical cascade multilevel inverters. The switching operation principle, modulation technique and control scheme under an unbalanced power operation among the cell are addressed. Simulation and experimental validation results in a reduced-scale power single-phase converter prototype under variable conditions at different set points for both PV strings are presented. Finally, a comparative numerical analysis between other T-type configurations to highlight the advantages of the studied configuration is included.
