註釋

[ANGLÈS] This work deals with the design, simulation and mounting of a small system that is part of a power control and distribution unit (PCDU). In particular, the system will limit the current and it will disconnect the load when a situation of overcurrent or short circuit occurs. The proposed system, that uses thermistors, allows the current limitation to meet all the specifications in a wide range of temperatures. The system has been thought for being used in spatial equipment. All simulations meet the specifications. In addition, the mounted circuit's measurements show the proper functioning of all the parts, with the exception of the transistor in charge of the current limitation. Most probably, there is a variation between the physical device and the simulated model. However, many more tests would be necessary in order to determine the problem source.
