Abstract

In this paper, two control strategies for BLDC motor drive have been implemented. One of the control strategies is based on PFC-CUK converter fed PMBLDCM drive and another one is PFC-interleaved boost converter fed BLDC motor drive. Comparison has been made between the two control strategies in terms of Torque ripple, Power factor for different operating speeds. The proposed work has been implemented under MATLAB/simulink environment. Simulation results are presented to validate proposed work. From the results, it is observed that PFC interleaved Boost converter fed BLDC motor drive is more effective compared to CUK converter fed BLDC motor drive.

Abstract

Objectives: This paper proposes a concept of micro-grid under smart distribution environment conditions with distributed generation resources like solar, wind etc. Methods/ Statistical Analysis: In present scenario, the importance of distribution sources is very high for maintaining the system reliability and also for providing backup generation under islanding condition and also as well as in grid-connected conditions. Findings: In this paper, a new control concept has been proposed for the seamless transfer who is based on Phase-Locked Loop (PLL) control for islanding and grid connected modes. In this paper the phase locked loop is used to maintain phase synchronization between grid and load voltages under grid and islanding conditions. And also, this paper proposes a current and voltage controller for stability analysis. The proposed method interfaces the PV system to the grid effectively. This proposed system is implemented and verified by using Matlab/Simulink. Applications/ Improvement: The proposed architecture is greatly beneficial for practical implementation of standalone and Islanded hybrid systems.
