Abstract:

Low voltage inverter for mechatronic actuation systems The scope of this thesis work is to implement a complete design of a low voltage inverter in general for any type of mechatronic system, although in this case the application is about three-phase motor of an e-bike. Structure and main arguments: The work is structured in three phases: a brief introduction with some researches about the existing circuits and the required elecronics, the electronic design and some tests and simulations, the PCB design and final results. - In the first part there are some descriptions about the typical problems related to the electronic devices used in the inverter design (in particular, the gate drivers have a lot of details to be careful) like current and voltage values or switching frequencies and so on. - For the electronic design, after a comparison of different gate drivers and power mosfets through datasheet of these components, I have verified with a simulink model some important parameters, like current limits and delays, of the total system or specific components. I have checked also other device performances to be sure that the selected components are the best for this application. At the end of this part I have obtained the final model composed by the microcotroller, the inverter and the motor load. - In the final part i have built the total pcb of the system that can be connected to the microcontroller and the motor. I have choosen the appropriate footprints for each component, respecting all design rules to design the tracks. At the end i have done also the thermal validation to be sure that all the components don’t get too hot.
