New current-mode current-controlled filters using the current-controlled conveyor
International Journal of Electronics, 1998New current-mode current-controlled filters are proposed. The proposed realization requires three dual-output positive/negative-type current-controlled current conveyors (CCCII±) and can simultaneously realize low-pass, high-pass and band-pass responses. Realization of notch and all-pass responses is feasible. The parameters ω0, ω0/Q0 and the band-pass

2014 IEEE Applied Power Electronics Conference and Exposition - APEC 2014, 2014
“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 ...

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.

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 ...

A current-mode CMOS fuzzy logic controller
International Journal of Automation and Control, 2008In this paper, design and simulation of a current-mode CMOS Fuzzy Logic Controller (FLC) is presented. The proposed controller is composed of Membership Function Circuit (MFC), fuzzy inference engine with min-product method and current-mode defuzzification circuit.

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.

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.
