Steady state analysis & design of switched capacitor DC-DC convertors

IECON'99. Conference Proceedings. 25th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.99CH37029), 2003
This paper presents a new approach to modelling switched capacitor (SC) DC-DC power converters in the steady-state. The distinguishing feature of SC DC-DC converters, i.e., no inductance elements and therefore the relationship in electricity quantity among the component capacitors can be determined, is made full use of, thus the analysis is much ...

Comparative assessment of zero voltage switched off-line power convertor topologies

IEE Proceedings B Electric Power Applications, 1992
Four half-bridge zero voltage switched (ZVS) convertor topologies are compared for offline applications in the 100–200 W range at a full-load switching frequency of 1 MHz. First, the quasi-resonant convertor (QRC) and the parallel-loaded resonant convertor (PRC) are studied.

Observer-Based Control for Cyber-Physical Systems With Periodic DoS Attacks via a Cyclic Switching Strategy

IEEE Transactions on Automatic Control, 2020
This article studies the observer-based output feedback control problem for a class of cyber-physical systems with periodic denial-of-service (DoS) attacks, where the attacks coexist both in the measurement and control channels in the network scenario ...

Analytical minimal loss design of transformers for high frequency switch mode convertors

Proceedings of 1995 IEEE Applied Power Electronics Conference and Exposition - APEC'95, 1995
The transformer design philosophy presented is based on fundamental principles and facilitates the design of close to optimum transformers, without significant iteration. No new theoretical material is presented, but rather an analytical procedure that accords priority to minimising losses. The power transfer capacity of a transformer is constrained by

On the reduction of component count in switched capacitor DC/DC convertors

PESC97. Record 28th Annual IEEE Power Electronics Specialists Conference. Formerly Power Conditioning Specialists Conference 1970-71. Power Processing and Electronic Specialists Conference 1972, 2002
Conventional switched capacitor power convertors are unsuitable for many practical applications because of their large component count. A new modified topology is proposed for step-down DC/DC switched capacitor power convertors using a multistage structure of switches and capacitors.

Educational workbench for testing the control techniques of switched DC/DC convertors

Proceedings of the 1993 Power Electronics Congress (Congreso Internacional de Electronica de Polentia), 2002
In this paper an educational workbench is presented. Its purpose is to develop several practice exercises about DC-to-DC converter control. This system allows one to analyze most of control techniques of nonresonant switched converters. Modular and trainer-oriented design and intrinsic security have been the most important points during the workbench ...

Analysis of buck/boost zero-current-switching resonant DC/DC convertor

IEE Proceedings B Electric Power Applications, 1989
A large signal steady-state analysis is presented for a buck/boost zero-current-switching resonant DC/DC power convertor. The basic equations governing convertor operation are derived. The following performance parameters are determined for lossless operation: current and voltage waveforms, peak currents and voltages of the switch and rectifier diode ...

On the reduced component count and low loss switched capacitor DC/DC convertors

Proceedings of Second International Conference on Power Electronics and Drive Systems, 2002
A very large number of components, in the conventional switched capacitor DC/DC stepdown convertor, make them unsuitable for practical applications and implementation in the integrated circuit form. Large ripple and charge-up losses result because of the in-series charging and parallel discharging into the load.

Prescribed Performance Fault-Tolerant Control of Nonlinear Systems via Actuator Switching

IEEE transactions on fuzzy systems
This article investigates a prescribed performance control (PPC) problem of nonlinear strict-feedback systems subject to actuator faults. By introducing $ln$-type performance functions, a constraint of output tracking error is established to prescribe ...
