Abstract

This paper presents an analysis of a low-cost photovoltaic energy processor designed to power household appliances within a community kitchen. The topology has two stages, its first one is a DC/DC Boost converter which conditions the voltage in strings from four photovoltaic panels in series to produce a voltage of VDC = 250 V at the DC-bus; the second stage consists of an inverter that converts direct voltage from the DC-bus into an alternate voltage with a three-level square waveform 220 V RMS. Due to both the low durability of the lead-acid batteries from the deep discharge and the high cost of the batteries with a longer life span, the proposal aims to avoid the usage of batteries. Therefore, there is going to be energy available for the system whenever there is suitable solar radiation. Regarding the application, it is fundamental to have knowledge of the power consumption from the household appliances. This information can be found in the manufacturer catalog. Respecting the electronic circuit, studies show the qualitative, quantitative and an example of the project with an output power of 2 kW, including an experimental test with the implementation of the inverter designed.
