Currently there is an increase in the demand for electric vehicles that require greater autonomy for driving. The use of suitable devices for energy recovery is crucial to guarantee the autonomy of electric vehicles (EV). In this paper, regenerative braking is used as an energy recovery strategy in an electric vehicle that uses a BLDC motor and a three-phase inverter for control it. The comparison of the inverter was made using SIHP22N60AE-BE3 MOSFET's and the IRAMY20UP60B module that uses IGBT's (with similar characteristics) The experimental results confirm that the module IRAMY recovers slightly more energy than MOSFET's. Therefore, it is determined that using the IRAMY module improves the amount of energy recovered after a braking situation for a braking cycle of 1s, 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 EV were done with no mechanical load.
