Improved Harmonic Performance in a Reduced Switch Matrix Converter with Space Vector Modulation

A new design of three phase modified matrix converter based on use of fewer semiconductor switches has been introduced in this study with an aim of improving efficiency, simplify circuit architecture and reduced overall cost of implementation. Traditional direct matrix converters (DMCs) typically need 18 bidirectional switches and net result is complicated control programs and elevated losses of power. Reduced-switch topology conversion of AC to AC will save the DC intermediate link in the architecture and simplifies the architecture, offering higher reliability. With a low number of active components, the design is capable of less switching losses and complexity of hardware. The different converters proposed, standard voltage source inverters (VSIs), current source inverters (CSIs), and typical DMCs are thoroughly compared. The key performance indicator total harmonic distortion (THD), system efficiency, control complexity. Simulation results show that the new structure has the same level of performance as the current solutions but possesses all the major benefits of compactness and ease of management, which makes it applicable in motor drives, renewable systems, and other space-limited applications.
