Analysis And Performances of DC-DC Converters for Variable Speed Drive Applications.

Abstract

This project improves the quality and performance of the power system by using four quadrant chopper circuit in the dc link of the variable speed drive systems. It also affects on reducing the ripple factor for the current and voltage in DC –link is illustrated .In this project we also evaluate the performance of variable speed drive systems is simulated and designed with the proposed chopper circuit. Further we observe the control system of pulses for the transistors is determined. And at last we discussed of the results introduced. The simulated result shows the advantages of proposed chopper circuit with variable speed drive systems. Finally the proposed method over the other newly suggested techniques are analyzed by several simulation scenarios.
