Current mode control of frequency controlled resonant converters
INTELEC - Twentieth International Telecommunications Energy Conference (Cat. No.98CH36263), 2002This 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.

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

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, 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.

Sensorless field oriented control using common mode currents
Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002A simple sensorless field oriented control technique of an induction motor drive is presented, that estimates the angular frequency of the main flux from common mode currents. The proposed technique is effective at any load level and any speed, ranging from zero to rated value and beyond, in the flux weakening region.

Cascadable Current-Controlled Current-Mode Multifunction Filter Using CDTAs
2007 International Symposium on Integrated Circuits, 2007The cascadable current-controlled current-mode multifunction filter with three inputs and one output using current differencing transconductance amplifiers (CDTAs) as active components is presented. The proposed configuration comprising only three CDTAs and two grounded capacitors provides low-input and high-output impedances, which is advantageous ...

Electronically Controllable Current-Mode Instrumentation Amplifiers
2018In this chapter, Current-Mode Instrumentation Amplifiers (CMIAs) with the capability of having an electronically controllable gain are discussed. These CMIAs do not require variable passive resistors to change gain but the latter is adjusted by means of a control voltage or current.

Current mode controlled bidirectional flyback converter
20th Annual IEEE Power Electronics Specialists Conference, 2003A description is given of a current-mode-controlled bidirectional flyback converter handling different values of power in either direction. The flyback transformer operates in a continuous conduction mode in one direction and in a discontinuous conduction mode in the other direction of power flow.

A PLL-based current-mode PWM circuit suitable for current-mode controlled techniques
2008 9th International Conference on Solid-State and Integrated-Circuit Technology, 2008A wide-range current-mode pulse-width modulation circuit for current-mode controlled techniques is presented in this paper. The proposed circuit has been designed and implemented using 0.35-?m CMOS 2P4M process. The core die size is around 95×115 ?m2 . The experimental results show that the variation of the output frequency within ±0.25%.
