Steady State Performance and Simulation of Matrix Converter for Various Load

The matrix converter is superior to the PWM inverter drive, because of regeneration ability, sinusoidal input, sinusoidal output and highest limit of the voltage transfer ratio. This paper describes the basic operating principle with various load conditions. The matrix converter has received considerable attention due to th e following advantages. A large capacity and compact converter system can be designed because the system does not have any dc-link circuit and, as a result, does not need any energy storage component, such as a smoothing inductor or a smoothing capacitor. The system has high efficiency, because the number of devices connected in series is less in this system than in the conventional rectifier- inverter system. Four-quadrant operation is very easy. The theory of the three-phase to three phase matrix converter is dealt with and its switching angle equations are presented. Matrix converter operation is based on the calculated switching angles. Modeling and numerical simulations of converter loaded with passive (R. L) and active (induction motor) loads are performed. Simulation results are presented.
