Document Type and Number:
WIPO Patent Application WO/2024/016934
Kind Code:
A1
Abstract:
Disclosed in the present application are a circuit of a discharge resistor, a circuit design method and apparatus for a discharge resistor, and a device and a medium. The method comprises: acquiring distance boundary parameters of a circuit board of a discharge resistor, working condition parameters of the discharge resistor, and a temperature difference threshold; establishing a circuit pre-topology structure of the discharge resistor according to the distance boundary parameters and a power tolerance threshold, wherein the circuit pre-topology structure comprises a plurality of resistor units which are connected in series, and each resistor unit comprise a plurality of resistor subunits which are connected in parallel; according to the working condition parameters and the circuit pre-topology structure, determining a total resistance threshold for the discharge resistor, the total resistance value of the discharge resistor, and the resistance value and power of each resistor subunit; performing thermal simulation processing on the circuit pre-topology structure of the discharge resistor, so as to determine a temperature topology structure of the discharge resistor; according to the temperature topology structure, determining the difference between the highest temperature and the lowest temperature of the plurality of resistor subunits; determining whether the difference is less than the temperature difference threshold; in response to it being determined that the difference is less than the temperature difference threshold, determining the circuit pre-topology structure to be a circuit topology structure of the discharge resistor; and in response to it being determined that the difference is greater than or equal to the temperature difference threshold, adjusting the resistance values of the resistor subunits, so as to determine a circuit topology structure of the discharge resistor.
