Power converter design for eMotor test rig

Power electronics has revolutionized the way we transform, control, and distribute electrical energy. Inverters are a fundamental component in this landscape, enabling the efficient conversion of energy from DC to AC. Specifically, inverters accepting higher voltages, such as those at 800V, have sparked increasing interest in the automotive field because operating at 800V rather than the more conventional 400V enables several advantages, including support faster charging speeds and lower current requirements, enhancing energy efficiency and reducing energy losses. In order to ensure the correct operation of the inverter a control board is required. This board is a complex electronic unit that coordinates and regulates numerous processes within the inverter to ensure that the energy conversion occurs efficiently and safely. This thesis deals with the hardware design of a control board for a three phase inverter supplying an eMotor test rig. The rating of the inverter is 800V and can handle 360 Arms with a typical switching frequency of 20 kHz.
