Voltage regulation of a DC-DC Buck type converter for an electrocoagulation cell
Abstract
Electrocoagulation (EC) is an electrochemical process to destabilize contaminants present in water by applying electrical energy through electrodes immersed in water. One of the factors that emerge from the EC process is the supply of electrical energy, this is quantified by the current density, which relates the applied current and the area of the electrodes. Different authors suggest that, to obtain a better performance in the EC process, the current density should be kept constant. However, due to the variation in the resistivity of the water, there will be changes in the applied current density, decreasing the efficiency of contaminant removal. With the objective of keeping the voltage constant in an electrocoagulation cell, this work presents the modeling, design and simulation of PID and PD+GPI controllers for the regulation of the electrical voltage in the electrocoagulation process for the treatment of gray water by a Buck type DC-DC converter.Downloads
