Circulating Current Control of Parallel Connected Converters

2020 Fourth International Conference on Inventive Systems and Control (ICISC), 2020
Boost converters step up the input voltage given to them. They belong to the class of switched-mode power supply. Parallel connected DC-DC boost converters exhibit a large number of advantages including generation of high output current, increase in output power capability, etc. But certain problems arise during such a connection.

Current mode controlled bidirectional flyback converter

20th Annual IEEE Power Electronics Specialists Conference, 2003
A 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.

Predictive control of modular current source converters

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
Current source converters (CSC) are used in AC-Drives and Electrochemical applications requiring large and controlled currents. Usually, a controller/modulating block using pulse width modulation is employed to provide current control. Although, several works describing predictive controllers have been presented for both two-level and multilevel ...

Hysteresis current controlled three phase PWM converter

2016 IEEE 7th Power India International Conference (PIICON), 2016
The paper presents hysteresis current controlled 3-phase PWM converter. The switching control is applied on three-phase bi-directional switches, to attain sinusoidal I/P current at unity power factor. The dc-link voltage is controlled by outer loop PI controller. The converter can be used for bidirectional power flow.

Current controlled line converter using direct torque control method

European Transactions on Electrical Power, 2004
AbstractThe control system of a current controlled line converter is implemented using the direct torque control (DTC) method. Implementation of the converter flux linkage orientated control system combines the DTC method with the conventional field orientated vector control principle.

Floating current-controlled resistance converters using OTAs

AEU - International Journal of Electronics and Communications, 2008
Abstract A simple configuration to realize the floating resistance converters using operational transconductance amplifiers (OTAs) is introduced in this paper. Negative and positive resistances driven by both the voltage and current signals can be achieved in the same scheme. The magnitude of the resulting resistances can be electronically controlled

Current-mode control for multiple-output converters

IEEE Transactions on Aerospace and Electronic Systems, 1996
A small-signal model for multiple-output forward converter with current-mode control is derived. The model can accurately predict the small-signal characteristics for current-mode control. It is observed that the power stage pole-zero relative positions, which are critical to the compensator design, are not affected by introducing current-mode control.

Nonlinear current control of three phase converter

IEEE International Symposium on Industrial Electronics. Proceedings. ISIE'98 (Cat. No.98TH8357), 2002
The workhorse in static electric power processing both in AC-DC and in DC-AC power conversion is the three-phase full-bridge power converter. This paper is concerned with the strange behaviour of the tolerance band AC current control of a three-phase full bridge AC-DC power converter with six controlled switches and a high filter capacitor on the DC ...

A Simple Current Control for Matrix Converter

Conference Record of the 2006 IEEE Industry Applications Conference Forty-First IAS Annual Meeting, 2006
As the matrix converter performs electric energy direct transfer from the input to the output, the distortion and the unbalance of the input voltages affects directly the output of the matrix converter. This paper presents a new and simple current control for matrix converter based on the fact that if the magnitude of the output current space vector is
