Analysis of Regimes of Voltage Regulators with Limited Capacity Voltage Sources. Geometrical Approach
Author:
Abstract: In power supply systems with limited capacity voltage sources, the limitation of load power is appeared. The systems with PWM boost converters may be the example of ones. But, the boost converters have a nonlinear and two-valued regulation characteristic too. Therefore, it is necessary to correctly determine the regime parameters of the converter relative to maximum permissible load voltage and control pulse width. If such power supply system contains also a quantity of loads with individual regulated voltage converters, then an interference of the converters takes place on the load regimes. Therefore, it is important to carry out the analysis of interference and to obtain relationships for definition of converter parameters. In the present work the results of interpretation of changes or "kinematics" of load regimes are presented on the basis of a conformal and hyperbolic plane.
