At the approach, the WebLab allows the development of multidisciplinary experiments in control and automation areas that can be used as a tool for engineering education and for research projects. This first WebLab includes an application that allows the remote access using a page on internet for drive control of a DC motor. Using this application the user can perform experiments as the open loop test in DC motor in order to obtain non-parametric system model and tuning of PID controller to ensure efficient speed and position motor control.

The converter used has a single stage where the processing power factor correction stage of power and drive of the lamp are integrated. The integration aims to simplify the power converter and thus make it economically more attractive. The brightness control is provided by varying the duty cycle of drive the switches of the converter. Experimental results and computer simulation are presented at the end of this paper.

For this purpose, a mathematical development that takes in account the presence of harmonic components in the I2R losses calculation will be presented, so that the effects of the harmonic distortion in the power system components and consequently the impact on the power factor can be analyzed. Based on this study, a factor that evaluates the power quality performance in low voltage networks is presented. This factor is directly associated to the economical viability, once that it points when the losses minimization is interesting according to the cost/benefit ratio.
