Matrix converter switching and commutation strategies for grid integration of distributed generation

For the practical implementation of MCs, one of the challenges is the commutation process. In this chapter. solutions for the commutation process are developed. Two switching topologies are available. These are classified as the one degree of freedom topology (with one active device) and the two degrees of freedom topology with two active devices. Different types of commutation processes are explored in this chapter as shown in Fig. 6. 1. Initially. the discussion focusses on the overlap and dead-band commutations and then, based on their limitations, examines two-, three- and four-step commutation processes.However, as these existing procedures still have limitations, an improved four-step current sensing-based commutation process is proposed. The commutation process is extended on the 'n' -lime switching arrangement. For a clear demonstration of the proposed improved commutation methods, the stale machines and switching tables are shown in two- to 'N'-leg commutations, with a set of logical agreements developed for safe switching commutation [I]. The industrial success of the MC will depend not only on the commutation but also be contingent on the connection between them and the switches.
