Current Control Method of WRSM in High-speed Operation Range

Abstract

This Paper analyzes the characteristics of the WRSM in high-speed operation range. To verify the control characteristics of various WRSM models, the relative position of the central point of current limit circle and voltage limit ellipse is defined as M value and 3 models according to M-max value are designed through inductance change. Through the designed models, the current control method of 3-variables control for maximum power especially in high-speed operation range is presented.
