ABSTRACT
Multilevel inverters (MLI), when used in voltage source inverter, have acquired wide utilization in industries. They are used, to obtain higher-output voltage with less total harmonic reduction (THD) with an increased number of levels. The matrix converter is used for ac to AC converter for variable frequency drives basically giving a good power factor improvement. This chapter aims in developing a simulation model of the matrix converter, established in Matlab Simulink with proper modulation technique. This also deals in controlling a PV-integrated three-phase Cascaded H Bridge (CHB) inverter, loaded with a matrix converter using the proportional resonant (PR) controller and adaptive fuzzy PID controller. The PR controller is helping to remove the steady-state error, and the fuzzy has the advantage of updated PI parameters. The superiority of fuzzy is emphasised based on THD reduction as compared to PR regulator.
