The work deals with design of the hardware of the two-stage inverter, driving the Permanent Magnet Synchronous Motor (PMSM) in the electric formula race car. Utilising the modern Silicon Carbide devices, the power loss of the inverter was decreased by 30% while reducing the invertor size and weight compared to former solution. The design puts importance in overall system integration, manufacturability, ease of maintenance and compromise between price and performance. The thesis documents in detail the design process, providing the theory, computations and simulations preceding the important conceptual and design decisions. Output of the work is the inverter circuit schematic together with PCB design ready to be put into production.
