Convertidor electrónico embarcado con control bi-modal del almacenamiento de energía con implementación de estrategias V2G (Vehicle To Grid) y del motor del vehículo eléctrico sin sensor

Abstract

Due to environmental concerns, the research relative to the Electric Vehicle has been increasing steadily during the last years. The work presented describes the electronic converter and its controller for a Permanent Magnet Synchronous Motor (PMSM), like the ones used in EVs. Said controller contains advanced functions that allow for a cost reduction in the system and an increase in its reliability. The converter is formed by two parts: one used for driving the PMSM and the other one for charging the storage system of the EV. The functions of the controller designed for the converter are three. The first one consists on controlling the PMSM without the need of a position sensor. This would translate in a simpler system enhancing the reliability. The second function of the controller is to use the EV as a component of the smart communities, providing with grid active functions. The integration of the charger and the driving system is then discussed for a reduction in the number of components needed. Lastly, the last function is designed to detect and correct vibrations detected in the EV structure, using the PMSM's speed controller. Simulation and experimental results prove the good operation of the control strategies for the converter proposed.
