Desarrollo de un calentador de agua orientado al uso doméstico utilizando un convertidor resonante

Abstract

This investigation details the study, design, simulation and implementation of a system to heat sanitary water by electromagnetic induction, consisting of six subsystems that together run the heater. First the power circuit subsystem is powered by the electrical grid, which is responsible for generating a variable magnetic field and consists of a rectifier, filter and a class E resonant inverter; second the firing circuit subsystem, an array of resistors that allows to raise the voltage obtained in the control subsystem to properly activate the switch that is in the first subsystem; third, the synchronization subsystem indicates the time of activation of the switch of the first subsystem achieving the ZVS condition; fourth the conditioning subsystem, a set of circuits that allows accurate reading of sensor values by conditioning their signal and filtering to be used by the control subsystem; fifth the control subsystem, monitors the heater system variables and performs control actions on the activation of the switch of the first subsystem; sixth the supply subsystem, converts the voltage obtained from the electrical grid into voltage levels required for the operation of the control subsystems and firing circuit. This project contains equations that allow to size electronic components that make up the induction sanitary water heater for implementation, through the results obtained from the research carried out, allows a sizing of materials for higher power levels.
