Reverse Matrix Converter
  The Matrix Converter (MC) is an attractive alternative to the back-to-back converter because it can convert an AC voltage directly into an AC output voltage of variable amplitude and frequency without the need for an intermediate dc-link and capacitor. However, the most critical problem is the reduced voltage transfer ratio, which is defined as the ratio between the output voltage and the input voltage, and has been constrained to 0.866 when using linear modulation. Improving the voltage transfer ratio is an important research topic. One solution is indirect MC under reverse power flow operation, called reverse matrix converter (RMC). The RMC is controlled to supply a three-phase AC voltage and also guarantee sinusoidal input/output waveforms as well as unity input power factor.
