Predictive Digital Sliding-Mode Current Control

2007 IEEE International Symposium on Industrial Electronics, 2007
In this paper we present a digital sliding-mode control for current regulation of power switching converters. Quasi-sliding characteristics of discrete-time sliding control are minimized by means a predictive strategy, that avoids continuous sampling action of inductor current. This predictive control strategy doesn't need a previous knowledge of power

Digitally controlled current-mode quadrature oscillator

2017 International Semiconductor Conference (CAS), 2017
A digitally controlled current-mode quadrature oscillator (DCC-MQO) is proposed. The circuit consist of four cascaded log-domain first order low-pass filter and a digitally programmable current division network. The lossy log-domain integrator gain and time constant can be adjusted using the bias currents of the logarithmic and exponential building ...

Robust control of multimodule current-mode controlled converters

IEEE Transactions on Power Electronics, 1993
A robust controller for multimodule current-mode push-pull converters is presented. First, the small-signal equivalent circuit and the transfer function model of the multimodule converter system are obtained. Then, the selection of slope compensation and the model reduction are performed using the concept of dominant energy mode.

Current-controlled current-mode multiphase oscillator using CCCDTAs

2011 IEEE Symposium on Computers & Informatics, 2011
This paper presents a new current-controlled current-mode multiphase sinusoidal oscillator using current controlled current differencing transconductance amplifiers (CCCDTAs). The proposed oscillator circuit, which employs one CCCDTA, one grounded capacitor and one MOS resistor for each phase, can generate arbitrary n output current equal-amplitude ...

Combined lossless current sensing for current mode control

Nineteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2004. APEC '04., 2004
In this paper, we provide basic time domain analysis of the combined lossless current sensing scheme. When applied to current mode control, it is noted that the selection of the RC current sensing components is not limited by the matching condition. For reliable steady state operation, the choice of the RC components may be accommodated for better SNR ...

Current mode control of frequency controlled resonant converters

INTELEC - Twentieth International Telecommunications Energy Conference (Cat. No.98CH36263), 2002
This paper examines an implementation of the average current mode control (ACMC) in a frequency controlled series resonant converter used in a telecommunication rectifier. This control mode provides very fast output overcurrent protection and improves reliability of the series resonant converter.

Current Mode Control

1997
As pointed out in Chapter 6, the conventional PWM converters are in essence feedback control systems and can therefore be treated accordingly with the available analytical tools, provided some additional steps are taken. The major theme of these types of treatments center, in almost all cases, around two performance merits: output voltage DC regulation

Voltage and Current Regulations of Bidirectional Isolated Dual-Active-Bridge DC–DC Converters Based on a Double-Integral Sliding Mode Control

IEEE transactions on power electronics, 2019
In this paper, a novel control scheme of the bidirectional isolated dual-active-bridge (DAB) dc–dc converters is proposed to regulate the output voltage and current, based on a sliding mode (SM) control.

Simplified Load-Feedforward Control Design for Dual-Active-Bridge Converters With Current-Mode Modulation

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2018
Many power electronic systems require dual-active-bridge (DAB) converters with ultrafast dynamic response. This paper presents a load-feedforward control design for DAB converters with current-mode modulation, which can enhance the dynamic response to ...

Slide mode control via current mode control in DC-DC converters

IEEE International Conference on Systems, Man and Cybernetics, 2003
We first study the behavior of a current-mode-controlled boost converter and exhibit its chaotic behavior (when the duty cycle exceeds 50%). We then introduce a practical method (sliding mode control) aiming at totally eliminating chaos and at keeping the desired current-controlled property.
