Abstract
A computer system has processing circuitry to obtain a discharge request of a DC-link capacitor of an electric drive system; disconnect an electrical machine of the electric drive system; determine a q current for the electrical machine being sufficient to start rotation of the electrical machine; and actively discharge the DC-link capacitor by applying the determined q current to the electrical machine.
