"Bipolar-mode" transistors on a voltage-controlled scheme

IEEE Transactions on Electron Devices, 1981
A buried-gate vertical JFET (BVFET) operated under forward gate bias shows saturating or nonsaturating drain current characteristics simply by Changing the channel cross section area. BVFET with a proper channel cross section has similar characteristics to a "bipolar-mode" SIT (BSIT) or a depleted base transistor (DBT). A generalized picture is derived

Voltage Mode Controlled niPOL for Space Application

2019 IEEE International Conference on Distributed Computing, VLSI, Electrical Circuits and Robotics (DISCOVER), 2019
In the recent times, the use of non-isolated point- of-load (niPOL) converters fed from the Intermediate Bus Architecture is growing. This paper deals with the design and analysis of POL converter, operating at a high switching frequency to yield 3.3V/6A output from 5V supply. Regulation of the output was carried out by using Voltage Mode Control.

The incremental voltage control mode for PWM regulators

PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference, 2003
The possibility of direct connections in parallel and inherent overload protection, which are typical advantages of current-controlled pulsewidth-modulated (PWM) regulators, are obtained by another control technique that is based on the sensing of the voltage waveform across a capacitor ( Delta V mode).

Sliding mode voltage control in current mode PWM inverters

PESC `92 Record. 23rd Annual IEEE Power Electronics Specialists Conference, 2003
The 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 ...

Voltage mode controlled buck converter under input voltage variations

2015 IEEE 15th International Conference on Environment and Electrical Engineering (EEEIC), 2015
Power electronic converters play a vital role in a power system and the most commonly used type of DC/DC converters is buck converter. This is due to the fact that buck converters are widely used to step down the voltage as well as they provide good voltage regulation in critical applications including power supplies for data centers.

The PFC with Average Current-Mode and Voltage Fuzzy Controller for the Output Voltage

2008 Second International Symposium on Intelligent Information Technology Application, 2008
The paper presents a PFC (Power Factor Correction) that uses Average Current-Mode control. The PFC strategy uses PI controller to correct the input current shape and a fuzzy controller to control the output voltage. Since the performance of fuzzy logic controller only depends on the selection of membership function and the inference of fuzzy rules ...

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.

Terminal Sliding Mode Controller for Voltage Control of Island Microgrid

2019 27th Iranian Conference on Electrical Engineering (ICEE), 2019
This paper proposes a robust method for voltage control of an island Microgrid. An island microgrid is a localized group of electricity sources and sinks (loads) that typically operates disconnected from the traditional centralized grid (macrogrid), and maintains operation autonomously as physical and/or economic conditions dictate.

CMOS IMPLEMENTATION OF A VOLTAGE-MODE FUZZY MIN-MAX CONTROLLER

Journal of Circuits, Systems and Computers, 1996
In this paper, a general-purpose fuzzy min-max network using a Gaussian-type membership function fuzzifier is proposed. Particularly, CMOS implementations of the Gaussian-type membership function fuzzifier circuits, min-max operators, and the defuzzifier circuit are analyzed.

A Voltage Controlled Oscillator with Up Mode Type Miller-Integrator

IEICE Transactions on Electronics, 2005
In this paper, we propose a voltage controlled oscillator (VCO) with up mode type Miller-integrator. The controlled voltage of this VCO can continuously change 0 V center in the positive and negative bidirection. Also, the relationship between control voltage and oscillating frequency shows the good linearity, and the calculated and the measured values
