Design and Development of Rotating Magnetic Field Inverter for Voltage Regulation
Abstract
In this paper, a novel of rotating magnetic field inverter is proposed. The working principle of inverter is based on the field modulation technique that is changing flux in a coil induces an emf in it. The proposed inverter deals with power quality issues such as voltage sags and swells, harmonics, transients and voltage fluctuations in the distribution line. The inverter is composed of groups of coils arranged in a circular pattern and an output inductive coil is placed in the center. The rotating magnetic field in the outer groups of coils cuts the output central coil, an emf is induced in it due to varying field. The rotating magnetic field inverter work as a dynamic voltage restorer to compensate the voltage dips by injecting power into distribution lines and vice versa. Comparing with the traditional DVRs, it consumes less power, highly efficient and have less circuit complexity. The whole model and architecture of RMI is being discussed. The validity of the proposed methodology is verified using MATLAB simulation.
