Initial results from a prototype corresponding to an induction water heater

Abstract:

It is clear that the development of new methodologies that increase the electrical systems efficiency and the welfare of users, avoiding pollution as best as possible, are highly desired by researchers and utilities. In this context, in Ecuador, basic service elements like water heaters are usually used by population. Where, currently water heaters based on Liquefied Petroleum Gas (LPG) are used. However, these devices are harmful for the country's economy. In this research, a novel prototype corresponding to an induction water heater is proposed. This has three operation stages corresponding to rectification, filtering, and controlling single-phase inverter by sinusoidal pulse width modulation (SPWM). In order to validate the proposed work, different test at each operation state, were developed. Results show an acceptable performance. Therefore, the prototype can be considered as an alternative to traditional devices.
