  • SAFETY CIRCUIT FOR AN ELECTRICAL TRACTION SYSTEM AND METHOD FOR CONTROLLING THE SYSTEM
    Publication number: 20230278430
    Abstract: A safety circuit for a high-voltage electrical traction system comprising a plurality of electric machines. The safety circuit comprises a primary high voltage interlock loop (HVIL) circuit configured to be connected to a battery and for each of the plurality of electric machines, a secondary high voltage interlock loop (HVIL) circuit, wherein each secondary HVIL-circuit is controlled by a corresponding switch unit configured to break the secondary HVIL-circuit if a fault in a corresponding electric machine is detected, and wherein the switch unit comprises a trigger device configured to break the primary HVIL-circuit if the switch unit is opened.
