New family of zero-current-switching PWM converter
(1999-12-01)
A new family of dc-to-dc pulse-width-modulated (PWM) converters is presented. These converters feature soft-commutation at zero-current (ZC) in the active switches. The new ZCS-PWM Boost and new ZCS-PWM Zeta converters, ...
Switching controllers based on neural networks estimates of stability regions and controller performance
(Springer, 1998)
This paper presents new results on switching control using neural networks. Given a set of candidate controllers, a pair of neural networks is trained to identify the stability region and estimate the closed-loop performance ...
Robust Control of Switched Linear Systems with Output Switching Strategy
(2015-10-29)
This paper investigates the robust control problem of continuous-time uncertain switched linear systems, using only a switching strategy depending on the plant output. The proposed method is based on linear matrix inequalities ...

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 ...
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 ...
The ZVS-PWM commutation cell applied to the DC-AC converter
(1997-12-01)
This paper presents the analysis of a dc-ac converter using a zero-voltage-switching (ZVS) commutation cell. First, we show the cell applied to the buck converter. The stages of operation are presented along with the main ...
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 ...
Robust switched control based on strictly positive real systems and variable structure control techniques
(2016-08-01)
This paper is concerned with the design of variable structure controllers for uncertain switched linear plants. The proposed method is based on Lyapunov–Metzler inequalities and on properties of strictly positive real (SPR) ...
