A High-Speed Current Regulator Based on a Buck DC-DC Converter Using a Direct Deadbeat Control

The paper presents analysis and design of a high-speed current regulator based on a buck DC-DC converter using a direct deadbeat control technique. The large signal mathematical model of the closed-loop current regulating system is developed in the form of nonlinear difference equations. The results of computational experiment obtained for dynamical operation mode under large disturbances at the source and load sides show a high efficiency of the proposed control method.
