A new current-mode control for DC/DC converter
INTELEC 05 - Twenty-Seventh International Telecommunications Conference, 2005Current-sensing is used widely in smart power chips, especially in DC/DC converter for voltage regulator modules (VRM), implemented with interleaved synchronous rectifier buck converters. The interleaved technique main difficulty is due to its current-sharing control between the several modules.

Slide mode control via current mode control in DC-DC converters
IEEE International Conference on Systems, Man and Cybernetics, 2003We 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.

A novel current-mode techniqe for controlling the average value of converter switch current
1993 IEEE International Symposium on Circuits and Systems, 2002A new current-programmed control technique for controlling the average value of converter switch current is presented. Based on this technique, a control loop that controls the average value of the output current in a Cuk converter is synthesized in the case of fixed frequency operation.

Sliding mode voltage control in current mode PWM inverters
PESC `92 Record. 23rd Annual IEEE Power Electronics Specialists Conference, 2003The author discusses the application of sliding-mode control techniques to DC-AC converters, driven by dual current mode PWM modulators that maintain constant frequency operation and provide output current clipping facilities. Sliding-mode control is advantageous when the inverter is designed to perform as a switching power operational amplifier, or ...

Lossless current sensing and its application in current mode control
2008 IEEE Power Electronics Specialists Conference, 2008In this paper, it is revealed that the lossless current sensing structure is very similar to the well known Maxwell bridge. The matching condition in lossless current sensing is the same as the balance equation in Maxwell bridge. In practice, it is difficult to meet the matching condition due to the parameter value variations. However, it is shown that

Current-controlled current-mode multiphase oscillator using CCCDTAs
2011 IEEE Symposium on Computers & Informatics, 2011This 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 ...
