Title:
PARAMETER DETERMINATION METHOD FOR DISCHARGE RESISTORS BETWEEN DIRECT-CURRENT BUSES, AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/193583
Kind Code:
A1
Abstract:
A parameter determination method for discharge resistors between direct-current buses, and a related apparatus. The parameter determination method comprises: first determining an upper limit model and a lower limit model of discharge resistors, and obtaining calculation parameters required for the two models, wherein the calculation parameters comprise a maximum direct-current bus input voltage, a discharge resistance precision, a capacitance value of a capacitor between direct-current buses, a capacitance precision, maximum allowable power during the discharge of a single resistor, and a set discharge time; then inputting the parameters into the upper and lower limit models to calculate upper and lower limit relation formulas of resistors; and determining, according to the upper and lower limit relation formulas, a resistance value of a resistor and the number of resistors connected in series and in parallel.
