Abstract

Inductors play a major role in the power electronics domain, particularly in DC-DC converter design. The objective of this paper is to reach inductance value by means of fewer turns, using Litz wire wound on a ferrite core. In the manufacture of inductors, the key aspects of the design criteria include the choice of the core material, the type of copper coil and insulation materials, and their overall size. Taking into consideration the design parameters with no compromises on performance, Litz wire with the least turns is introduced into an inductor in certain DC-DC converters. Once the DC settled voltage is reached, it is given to a single-phase inverter for loading and application measures. This approach provides a small-level inductor design for maximized efficiency with improved thermal behavior. The hardware model for the proposed method has been developed using a DC-DC converter fed with a single-phase inverter model. The proposed DC-DC converter has been tested, performance-wise, by applying different load levels. It is observed, from the results, that the Litz wire-based approach achieves maximum efficiency with improved thermal behavior.
