In order to increase the output voltage in frequency converters without DC-ESE, the concept of the family of matrix-reactance frequency converters (MRFC) has been proposed [32–34]. The topologies of the MRFC are based on three-phase unipolar MRC structures [24–26], and are derived by implementing a matrix-connected switch set (MCS) instead of one input or output switch set in the MRC [32]. In this way, it is possible to obtain load voltage frequency change, as is the case in a MC, and a load output voltage much greater than the input voltage, as is the case in MRC.
