Comparación de recuperación de energía en el sistema de freno regenerativo en un vehículo eléctrico utilizando dispositivos mosfet y el módulo inversor iramy

Abstract

There is currently an increase in the demand for electric vehicles that require greater autonomy when driving them. The use of suitable devices for energy recovery is crucial to guarantee the autonomy of electric vehicles (EV). In this work, regenerative braking is used as an energy recovery system in an electric vehicle that uses a BLDC motor and a threephase inverter for its control. The comparison of the inverter was made using SIHP22N60AE-BE3 MOSFET devices and the IRAMY20UP60B module that uses IGBT devices (with similar characteristics) The experimental results confirm that the module that from now on we will call IRAMY recovers slightly more energy than MOSFET devices. Therefore, it is determined that using the IRAMY module improves the amount of energy recovered after a braking situation for a braking cycle of 4s, with a duty cycle of 40%, a braking torque of 30Nm and 78RPM, and, although , the amount of energy recovered is not significant between these devices, for braking situations with higher torque, and in longer periods of braking, the autonomy of the EV is improved. For this work, the tests performed on the VE were done with a mechanical load of 25Kgr.
