Robust control of current-mode controlled converters
Proceedings Eighth Annual Applied Power Electronics Conference and Exposition,, 2002A robust controller for multimodule current-mode push-pull power converters is presented. First, the small-signal equivalent circuit and transfer function model of the converter system are found. Then the slope compensation is selected and model reduction is performed using the concept of dominant energy mode.

Current-sensing technique for current-mode controlled voltage regulator modules
Microelectronics Journal, 2008This paper introduces an innovative current-sense technique for voltage regulator modules (VRMs). The proposed method is applied to a multiphase buck converter although the converter topology does not affect the accuracy or effectiveness of the proposed technique.

“Peak Current Mode Control” (CPM) is usually implemented in analogue and brings the advantage of cycle by cycle protection, higher bandwidth rejection of input voltage disturbance or equivalently increases a converter's input impedance. “Average Current Mode Control” (ACM) allows inductor current control to a “true average” and will facilitate an ...

2006 29th International Spring Seminar on Electronics Technology, 2006
This paper presents a comparison between two active power factor correction methods. Active power factor correction can be realised using a variety of converter topologies. The boost converter is used in this paper and a direct comparison between two circuits that realise the borderline current mode control and the average current mode control is ...

Current mode control of switching regulators
Radio and Electronic Engineer, 1984By adapting the forward converter range of switching regulators to include an additional current-controlled feedback loop, derived from either the secondary or primary power circuit, an improvement in the closed-loop performance of the switching regulator can be obtained.

VDIBA-Based Current-Mode PID Controller Design
Journal of Circuits, Systems and Computers, 2023This paper aims to bring a voltage differencing inverting buffered amplifier (VDIBA)-based current-mode (CM) proportional integral derivative (PID) controller circuit. This CM PID controller is designed with a single VDIBA, three resistors, and two grounded capacitors.

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

A NEW CURRENT-MODE CURRENT-CONTROLLED ALL-PASS SECTION
Journal of Circuits, Systems and Computers, 2007This paper presents a new translinear-C current-mode first order all-pass filter suited for high frequency operation. The new circuit offers a simpler structure than the available translinear-C works. The pole-frequency of the circuit is controllable over a wide range through external bias current of CCCII and the circuit possesses low THD for a wide ...

Application of slide mode control to a current-mode-controlled boost converter
IEEE 2002 28th Annual Conference of the Industrial Electronics Society. IECON 02, 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.
