Design and implementation of a dc-dc converter based on variable structure control of switched systems
(2011-12-01)
This paper presents a control method for a class of continuous-time switched systems, using state feedback variable structure controllers. The method is applied to the control of a non-trivial dc-dc power converter and a ...
Robust H∞ Switched State-feedback Control of Uncertain Linear Systems
(2018-01-01)
This paper addresses the issue of robust H∞ control for a class of continuous-time uncertain switched linear systems. A set of state-feedback gains and two switching rules are designed to render the closed-loop system ...
Zero-Current Switching (ZCS) for a High Step Ratio Modular Multilevel dc-dc Converter with wide voltage range operation
(IEEE, 2020)
The rise of new dc technologies is pushing the development of highly efficient dc-dc converters, especially at high voltage and high step ratio. Modular multilevel converters (MMCs) are an attractive alternative because ...
Suboptimal Switching Control Consistency Analysis for Switched Linear Systems

Boundary Control of Full-Bridge ZVS: Natural Switching Surface for Transient and Steady-State Operation
(Institute of Electrical and Electronics Engineers, 2014-02)
This paper presents the use of a high-performance boundary controller for the full-bridge zero-voltage-switching topology. An enhanced dynamic response is obtained by employing the natural switching surface (SS), which is ...
A clean four-quadrant sinusoidal power rectifier using multistage converters for subway applications
(2005)
A special 27-level four-quadrant rectifier for subway applications is analyzed. The arrangement uses only three H-bridges per phase, common dc bus, and independent input transformers for each H-bridge. The transformers ...
Switching Control Strategy to Minimize Dual Active Bridge Converter Losses
(Institute of Electrical and Electronics Engineers, 2009-07-31)
A switching control strategy to control the power flow and minimize the total power losses of the dual active bridge converter topology is proposed in this paper. The control strategy consists of driving the bridge with ...
Observer-based control design for switched affine systems and applications to DC-DC converters
(2013-08-01)
This paper deals with the problem of establishing a state estimator for switched affine systems. For that matter, a modification on the Luenberger observer is proposed, the switched Luenberger observer, whose idea is to ...
