Interleaved dc-dc Converters for Photovoltaic Modules

2007 International Conference on Clean Electrical Power, 2007
In the present paper, an application of interleaved dc-dc converter in photovoltaic (PV) modular system has been presented. In the multi-string technology, several PV strings are interfaced with their own dc-dc converter to a common dc-ac inverter. Enlargements are easily achieved since a new string with dc-dc converter can be plugged into the existing

Systematic Analysis of Interleaved Digital-to-Analog Converters

IEEE Transactions on Circuits and Systems II: Express Briefs, 2011
A generalized theoretical analysis of interleaved digital-to-analog converters (DACs) is presented to explain the cancellation of image replicas. A new RF-DAC architecture comprising N -parallel DACs and using both clock and hold interleaving structure is proposed.

Analysis of interleaved converters with WTA-based switching

2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003
This paper presents interleaved buck converters using a switching rule based on winner-take-all nonlinearity. The switching rule can realize flexible phase control and the system can generate various interesting synchronous phenomena. Using a simple piecewise constant model, we clarify parameters conditions for existence and stability of the phenomena.

Multifunctional interleaved boost converter for PV systems

2010 IEEE International Symposium on Industrial Electronics, 2010
In this study, an interleaved boost converter cascaded with a battery charger buck converter is designed and implemented. The converter also has maximum power point tracking capability and the battery charge operation is designed for purpose of long life requirements of batteries.

ROBUST CONTROL OF INTERLEAVED SYNCHRONOUS PWM BUCK CONVERTERS

Control and Intelligent Systems, 2007
The problem of controlling interleaved buck power converters is considered. The aim is to regulate the output voltage of the converter and to ensure an adequate current sharing between its different channels. The control law is designed from the large-signal bilinear model (of the whole multi-channels converter) using the backstepping technique.

Modular system of converters with interleaved structure

Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014, 2014
This article deals with modular system of DC-DC converters which contains more than one converter. It is possible to connect all converters in parallel for gain high output current, all converters in serial for high output voltage or various combinations to reach desired output voltage and current.

V/sup 2/ control of interleaved buck converters

Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003
This paper presents a simple voltage mode V/sup 2/ control method for controlling the 2-cell interleaved synchronous buck converters. It uses two feedback loops, similar to current mode control, one for slow outer loop and the other for the faster inner PWM control loop.

A parallel interleaving converter with soft-switching

2011 International Conference on Electric Information and Control Engineering, 2011
This paper proposes a soft-switching interleaved boost converter and control method, the converter has extensive applied foreground in the high-power (>1KW) single-phase PFC. It can turn on at zero current and turn off at zero voltage. The paper gives in detail the work theory of the electric circuit and the analysis of various mode, and gives the ...

A novel coupled inductor for interleaved converters

2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010
Aiming to reduce the volume and weight further, a novel coupled inductor is proposed in this paper. The implementation approaches and the operation principles are analyzed in detail along with the comparison analysis with three-leg coupled inductor.

Time-Interleaved A/D Converters

2005
In this chapter we have discussed the time-interleaved ADC. The performance is limited by mismatches between the channels. Gain and offset errors can be calibrated. A more severe problem is the phase skew errors which increases at high signal frequencies.
