Diseño, simulación y construcción de un conversor AC/DC con regulación en lazo cerrado, aplicado a una motocicleta de 100 CC.

Abstract

The objective of the present research was to design, simulate and build an AC / DC converter with closed-loop regulation, applied to a 100 CC motorcycle, for which the output voltage value of a commercial converter was obtained and carried out the development of this prototype using microcontrollers; The identification of the components of the AC / DC converter was carried out by research on the functioning and operation applied to the motorcycle industry. The technical requirements necessary for the motorcycle's operation were determined, using taking samples of the generated power. The converter circuitry was designed to ensure the interval operation between the maximum and minimum RPM. The converter control algorithm was developed using an I2C communication protocol, allowing the microcontrollers to divide their work tasks and obtain a regulated voltage at the output. The operation of the electronic system was simulated using Proteus, Arduino IDE for the control algorithms, and MATLAB to obtain parameters for the PID control. The prototype was built using IPC standards (Association Connecting Electronics Industries) for the elaboration and assembly of the PCB. The correct functioning of the prototype was evaluated using different road tests of the motorcycle. The T-student test was used for the statistical analysis, obtaining a significant difference between the commercial device and the prototype; four tests were carried out for each one; the most prominent were the first and second because they had a deficient absolute error. It is concluded that the use of the prototype presents a considerable improvement of 73,76% compared to the commercial device. In the systematization of the prototype, it is recommended to carry out new experiments with different samples in which other factors are considered.
