Modeling and Simulation of Frequency Converter Used In Speed Control of Asynchronous Motor
      Ankit Kumar Jain, Gutta Krishna Chaitanya, Vaddi Ajay Kumar
Abstract: Controlling the speed of the Induction Motor is very essential in today’s industry. Conventionally Gear box is used for speed control which consumes more energy. This Paper presents the Modeling and Simulation of frequency converter used for speed control of asynchronous motor through digital approach which has high reliability and energy conservation by using MATLAB/ SimulinkTM. The Frequency Converter is mainly used as variable frequency source to adjust the speed of asynchronous motors. The Frequency Converter circuit consists of three-phase Rectifier, IGBT module, DC link and the three phase inverter. The Transistor three-phase inverter converts the DC voltage into variable voltage and variable frequency (VVVF) power source. The commonly used Capacitors bank is replaced by the LC filter. The Inductor and the capacitor are used to reduce switching stresses so that during power up the voltage source inverter is protected by the inrush currents. The circuit is simulated and output results are obtained.
