Control of Industrial Drives through Multicell Impedance Source Inverter

Abstract:

In this paper, various power quality issues that occur while driving an industrial motor drive such as voltage sag, swell, interruptions are discussed. A solution for such issues is proposed drives during various conditions of power quality issues is discussed in detail and a comparison with traditional Z-source inverter is made. The results are validated for mathematically modelled using Multicell Z-source inverter. By controlling shoot-through duty cycle using various techniques such as Simple boost control, Maximum boost control, constant boost control these issues are addressed. Multicell Z-source inverter has come as a replacement for traditional Z-source inverter due to its less EMI noise; increased voltage level with increase in cell as well as reduced voltage stress makes it more advantages than traditional one. In this paper, control of industrial system of 3 kW induction drive in MATLAB/Simulink environment and the results are summarised.
