[ES] In the course of this master end work, a verifier will be designed for the master plate of a 3.6 kW on-board charger (OBC). This plate consists of a single-phase network inlet filter, a power factor correction (PFC), DCLink capability, a semi-bridge resonant converter, a diode rectifier, DC output filter, a control plate which monitors all critical system variables in HW and SW and finally the drivers switching the MOSFETs of both the PFC and the inverter. The purpose of this verifier is to make it industrialised, as its purpose is to be used in the MAHLE Electronics factory where around 400 OBCs per day are produced. Therefore, this verifier shall perform its function autonomously where the operator only has to change the plate to be verified and give approval to start the test. The verification shall consist of several stages, the first stage being the programming of the microcontroller of the plate. It is responsible for all system readings, not just voltage and current, if not safety parameters to prevent the equipment from being damaged. In the second part, the autoautomate presses the plate to check a bed of paints where the test points of the latter are attached to the project electronics. Finally, SW starts the step test and all readings and deeds are made so that the plate is verified and can be assembled on an OBC. For the whole system to work, a PCB with all the electronics needed to test all OBC functionalities has been designed. This plate has been designed using the design software “Altium”. It is the mother plate of the project, everything is managed through this PCBs so that, when the whole of the assembly is assembled, the plates can be checked smoothly. To establish communication between the plate to be checked and the computer, the USART communication protocol is used from the computer to Beckh-off. The latter is in charge of controlling all test inputs and outputs, as well as making readings, switching transistors to change any function, etc. From Beckh-off to the plate, the CAN Bus communication protocol shall be used, used for reading certain signals in real time as well as for activating or deactivating OBC functions and observing their behaviour.
