Title:
R/D CONVERSION METHOD AND R/D CONVERTER
Document Type and Number:
WIPO Patent Application WO/2021/124624
Kind Code:
A1
Abstract:
This R/D conversion method includes a step for removing, from digital angle values φ, a frequency band including a frequency component that is double the excitation frequency of an excitation signal for a resolver 30. The method also includes a step in which the resolver 30 outputs a resolver signal having a phase difference with the excitation signal that corresponds to the angle of the resolver. In a step for feeding back the digital angle values φ, the digital angle values φ are fed back to the resolver signal.
