“…Most modern isolated matrix inverters feature soft switching in semiconductors that is achieved using special modulation strategies [46][47][48][49][50][51][52][53][54][55][56], resonant circuits [60,66,80] or active auxiliary circuits [81][82][83][84][85]. In addition, these methods aim to reduce semiconductor voltage stresses [85].…”

“…The PSM modulation is usually based on only one shift carrier for the CSI [46,48], while in the VSI based topologies, PSM with more than one phase shift is typically used to achieve better quality of the output voltage [86]. More sophisticated methods additionally use FM to increase the ZVS range [66]; moreover, the amplitude modulation (AM) [80] was also addressed. These are the low-level modulation techniques that are employed in converter modulators to generate the switching sequence within a single switching period and ensure that an inverter can perform the input voltage regulation and the output current control (Figure 3).…”

“…In [80], the sine AM modulation (SAM) was proposed as an alternative approach for the conventional PWM with varied duty cycles. The topology consists of the PP configuration at the AC side and the FB with the parallel resonant tank at the DC side (Figure 17).…”

“…In [80], a topology consisting of the PP configuration at the AC side and the FB with the series resonant tank at the DC side is described (Figure 25). The series resonant tank is connected between the middle point of the bridge legs, transformer AC sidewinding and the middle point of the input voltage source.…”

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.
