Design of Home Appliances for a DC-Based Nanogrid System: An Induction Range Study Case

Abstract

Efficiency has become a key design parameter when designing any electrical system. In recent years, significant attention has been paid to the design of optimized micro and nanogrids comprising residential area subsystems. Among the different proposed approaches, one of the most promising consists of a dc-based nanogrid optimized for the interoperation of electric loads, sources, and storage elements. Home appliances are one of the main loads in such dc-based nanogrids. In this paper, the design and implementation of an appliance for operation in a dc-based nanogrid is detailed. An induction heating range is considered as a design example, with some of the design considerations generalizable to any other appliances. The main design aspects, including the inductor system, power converter, and control, are considered. Finally, some simulation and experimental results of the expected converter performance are shown.
