| Summary: | This project illustrates the use of Power System Block Set (PSB) within MATLab/Simulink. The Power System Block provides the ability to model and simulate electrical power system and drives within Simulink Environment. The SPMC as a direct frequency changer were used in this work and using three-phase AC-AC matrix converter and the resistor as a load. The TPMC circuit composed from nine ideal power switches used as a frequency converter. The desire output voltage will be synthesized using SPWM technique. It is well known that a PWM-controlled rectifier can offer advantages of reduced low-order harmonics and unity input power factor when compared to a conventional thyristor converter. However, theoretically optimum PWM strategies are often difficult to implement physically or are not easily extended to regenerative operation. This paper proposes an alternative PWM strategy based on AC-Ac matrix converter theory, which generates only high-order switching harmonics, presents a unity power factor to load to the supply, implicitly extends to regeneration (and operation with a center tapped DC output), and is feasible to physically implement for real-time output voltage control. Both the theory and physical simulation results are presented in the paper. |
