The thesis presents an overview of the current state of vehicle electrification and identifies the use of multi-motor drive trains in newer higher-performance vehicles as a potential challenge in designing DC distribution and selecting control algorithms. It has been shown that, due to the use of multiple inverters in which each has an energy tank in the form of a DC link capacitor, with the interaction of parasitic inductance of the wiring, resonances can occur. In extreme cases, resonances cause an increase in the current load of the capacitor and wiring above the design values. Observing the DC link circuit as a linear time-invariant system, and the inverter as a source of current excitation to that system, the paper tries to compare the spectrum of excitation and gain of the system to show the conditions under which the inverter will bring the circuit to resonance. Campbell diagrams were used to provide a clear image of the influence of the change in the electrical frequency of the motor on the excitation spectrum that the inverter injects into the DC link circuit at fixed switching frequencies. Using a complete simulation model that includes machine control, different combinations of motor speed and switching frequency were tested. For the most important criteria and as a measure of resonance, the alternating RMS value of the current in the DC link circuit was chosen. The thesis proposes a definition of a multi-objective function that takes into account machine current distortion and inverter losses as additional criteria to determine the operating range. Ultimately, the thesis proposes a measurement setup by which the frequency characteristics of a DC link could be measured without the need to disconnect a high voltage DC source.
