Voltage and/or current back-to-back converters are traditionally used to interface an ac source with an ac load. An energy storage element is used to couple the dc-link of the front-end ac-dc rectifier to the back-end dc-ac inverter. A matrix converter (MC), however enables ac-ac conversion without any intermediate energy storage element. Conventional MCs, known as direct matric converters (DMCs), are single-stage converters that connect an m-phase voltage source to an n-phase output load through an m x n array of bidirectional switches. On the other hand, an indirect matrix converter (IMC) requires separate stages for the voltage and current conversion. In this chapter, the most popular MC topologies along with their control and modulation strategies are presented. A brief discussion on the technological and practical issues facing MCs, and a comparative assessment of their performance with the voltage back-to-back converters is given.
