Implicit current DC-DC Digital Voltage-Mode Control

2014 IEEE 23rd International Symposium on Industrial Electronics (ISIE), 2014
Analog circuits have been dominating the switching power supplies control due to simplicity and low implementation cost. However, digital control presents important advantages to meet the increasingly stringent future processors power requirements. This study focuses in the fact that, sensing only a buck converter output voltage, a digital control can ...

Voltage stability and control modes in HVDC systems

POWERCON '98. 1998 International Conference on Power System Technology. Proceedings (Cat. No.98EX151), 2002
In this paper, according to the classical definition of the voltage stability of a load connected to a generator through a transmission line, a criterion called voltage stability index (VSI) which can be used to determine the voltage stability of the converter AC bus is proposed.

Instabilities in current-mode controlled switching voltage regulators

1981 IEEE Power Electronics Specialists Conference, 1981
A survey of the instabilities of switching voltage regulators with different types of current-mode controllers (including LC3 or constant-hysteresis; MC2 or constant-frequency and constant off-time versions) is presented. Apart from the well-known open-loop oscillation of the constant frequency regulator above 50% duty ratio, other instabilities can ...

Dual-Mode Voltage-Controlled Oscillator with Injection Lock

2005 IEEE Conference on Electron Devices and Solid-State Circuits, 2006
We present a new voltage-controlled oscillator structure featuring dual-mode outputs which are mutually locked to octave bands, while consuming only one current branch. The characteristics of coupled LC tanks are analyzed and a structure for realization of a low current dual mode oscillator is presented.

Current-controlled voltage-mode multifunction filter using CCDDCCs

2011 IEEE Symposium on Computers & Informatics, 2011
This paper presents a new voltage-mode multifunction filter with four inputs and three outputs employing three current controlled differential difference current conveyors (CCDDCCs) and two grounded capacitors. The proposed circuit can provide low-pass, band-pass, high-pass, band-stop and all-pass voltage responses by appropriately connecting the input

Polynomial Regression Controlled Voltage-Mode Flyback Converter

Flyback converter is one of the most preferred converter structures for low-power industrial applications. The input voltage and load, which are among the operating parameters of this converter, can vary, making the power control of the converter important. Various control techniques are used to control the flyback converter.
