Title:
FILAMENT CURRENT CONTROL METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/214204
Kind Code:
A1
Abstract:
A filament current control method and apparatus. The method comprises: obtaining a current filament current value (S11); determining a current range within which the current filament current value falls (S12); determining a corresponding relationship between a filament current and a control current according to the current range (S13); and determining the current control current according to the current filament current value and the corresponding relationship (S14). The problem of large filament current control errors caused by nonlinear characteristics of a filament transformer can be solved.
