Linear Boundary of Current Closed-Loop Control of Two-Quadrant H-Half Bridge Converter in Excitation System

Abstract:

The excitation system is an important component element that influences the dynamic behavior of alternators. However, when the two-quadrant H-half bridge converter is used in the exciter field current closed-loop control system, there will be some problems of nonlinearity. To prevent the converter from working in the nonlinear area, the working conditions of linear and nonlinear area of H-half bridge converter is discussed firstly in this paper. And then it is verified by the simulation results.
