AbstractA single-stage matrix converter (MC) is preferred for the conversion of a single-phase (1) supply of fundamental frequency (50 Hz) to the multiphase (m) power supply in a limited operating frequency range (5-15 Hz). These converters possess a limitation on account of voltage and current distortions when the converter is used up to fundamental or higher frequency operating loads. To resolve this problem, this letter proposes a dual-stage 1\emptyset\to\m\emptyset MC, which ensures improved power quality across the output voltage and current. This converter has a three-leg front-end side rectifier stage (RS) consisting of six numbers of common emitter configured bidirectional power semiconductor switches. A filter circuit is installed in between 1\emptyset supply and RS enabling to build positive average dc voltage across the virtual dc link while maintaining the source current profile. The second stage is an inversion stage having a conventional voltage source inverter structure. The proposed dual-stage MC topology is having a simple structure with the ability to convert the 1\emptyset supply to any number of desired output phases not only at the lower frequency but also at the fundamental and higher frequency. The practical applicability of the proposed dual-stage MC is validated through experimental results. 1986-2012 IEEE.
