Recently considerable interest is shown in the use of Matrix Converters for industrial drive applications. Since the inception, several carrier based modulation schemes have been proposed for Matrix Converters. The operation and control methodology of Matrix Converters are complex. This paper examines the various modulation schemes for three phase ac to three phase ac matrix converters starting from the Venturini and optimum Venturini algorithm to the recently developed Sunter-Clare and Ned Mohan algorithm, by modeling technique. The SIMULINK model simulation results are presented and the results are compared.

This manuscript describes modelling of a six step [5 -9]. Detailed SIMULINK model for PMSM drive fed by discontinuous current mode inverter fed PMSM drive using six step inverter with fixed switching angle is available in the SIMULINK. The dq-axis voltage-current and torque relation in literature reference [10]. SIMULINK models for PMSM drive terms of machine parameters are used to develop the SIMUlLINK fed by six step inverter with a PID controller is reported in the model. A six step 120 degree mode inverter model is newly literature, but lacks schematic details of PMSM and inverter developed using SIMULINK. Performance test and measurement were conducted on Lybotec six step discontinuous models [11]. current inverter fed PMSM drive at no load in the laboratory. These values are used in this open loop model. Simulation resultsThe object of this paper is to develop SIMULINK models for phase advance angle of i/6 and n/4 are given and compared for PMSM drives supplied by six step discontinuous current with experimental results. mode inverter with switching angle advancing facility and to study the performance by simulation and experiment.
