Abstract
The present application discloses a method for controlling filament current and apparatus. The method comprises: acquiring a current filament current value (S); determining a current range within which the current filament current value falls (S); determining a correspondence between a filament current and a control current according to the current range (S); and determining the current control current according to the current filament current value and the correspondence (S). The problem of large errors in the control of filament current caused by nonlinear characteristics of a filament transformer can be solved.
