Sliding-Mode Voltage Control of Dynamic Power Supply for CCM
2019
This paper presents a novel means of controlling a dynamic power supply in continuous conduction mode via sliding-mode voltage control technique. Previous work has discussed the design and implementation of a high-efficiency dynamic power supply based on an asynchronous buck converter in open-loop operation. This work incorporates nonlinear control design for the dynamic buck converter that suits applications such as envelope tracking and amplitude modulation for Class E power amplifiers. The control system is shown, via MATLAB simulation, to accurately track time-varying reference signals, improve the power converter dynamics, and provide the desired output power while rejecting large load disturbances.
