| Popis: | Industry based electronic drives plays a vital role in establishing the energy efficiency. Recently, the process has been established in the industries by using a brushless DC motor (BLDC), which enhances the overall system efficiency. Therefore, the process shouldleverage an excellent operation by using BLDC, which is controlled by z source network and voltage source inverter (VSI). BLDC has more features such as low inertia and friction, low radio interference, high reliability and high efficiency. Due to the absence of brushes, it does not require any practical maintenance. Since, it has some drawbacks like high cost, low starting torque when compared to conventional DC motor and also it has no flexibility control because of the absence of field winding. Hereby, to overcome the aforementioned drawbacks, Direct Torque Control (DTC) is introduced along with BLDC for improving its efficiency, when compared to other conventional control techniques. By using DTC technique, the ripples produced from torque can be reduced. Due to this reduction in ripple torque, the motor increases the speed and speed torque curve. The different aspects such as number of components used and stressing semi-conductive switches and the efficiency of the converter are restricted by each converter topology. Some of these converters are utilized for a range of industrial applications. Efficient power conversion is more important than ever due to the alternative energy sources such as diesel, solar, wind and ocean wave power, which require proper power conditioning in order to adapt to various loads. New applications of power converters remain very promising for electric vehicles. Thus, using the z source network and sensor-less technology, the device is optimized to power the BLDC engine. The simulation is done here with MATLAB/simulink to the z-source network dependent DTC for BLDC and the finding is confirmed by a theoretical review. |
