Title:
DC/DC CONVERTER STABILITY ANALYTICAL METHOD AND SYSTEM
Document Type and Number:
Japanese Patent JP2019140899
Kind Code:
A
Abstract:
To disclose DC/DC converter stability analytical method and system.SOLUTION: The method includes step S1 and step S2. The step S1 performs conversion derivation for a DC/DC converter system model, and acquires a DC/DC converter state spatial equation applied to discontinuity control theory stability analytical method. The step S2 determines exponential stability of the DC/DC converter system by using the state spatial equation of the DC/DC converter thus derived, by the discontinuity control theory exponential analytical method, and describes the DC/DC converter by calculating the DC/DC converter exponential convergence speed, and using the inventive discontinuity control theory. When analyzing the DC/DC converter, linearization of the system is not required, analysis for system stability becomes more accurate, and the analytic process is simplified.SELECTED DRAWING: Figure 1
