Variable interleaving technique for photovoltaic cascaded DC-DC converters
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014This paper introduces a variable interleaving technique for photovoltaic cascaded DC-DC converters. A series rather than parallel connection of converters allows higher switch utilization and lower rating of components; however, they suffer from nonhomogeneous irradiations condition.

Interleaved ZVS DC/DC converter with high input voltage
2012 IEEE International Symposium on Industrial Electronics, 2012An interleaved half-bridge converter is presented for high input voltage application. The features of the proposed converter are zero voltage switching (ZVS) turn-on for all active switches, ripple current reduction at output side, load current sharing and load voltage regulation.

Interleaved Bidirectional DC-DC Converter for Automotive Electric Systems
2008 IEEE Industry Applications Society Annual Meeting, 2008In this paper, interleaved bidirectional DC-DC converter with ZVT cell using a single resonant inductor in continuous conduction mode is proposed. The proposed interleaved bidirectional DC-DC converter has advantages such as a simple circuit, ZVS during wide load range and minimization of current injection effect by using dual current injection time ...

State-feedback control of an interleaved DC-DC boost converter
2016 24th Mediterranean Conference on Control and Automation (MED), 2016This paper extends a recently proposed statefeedback control design method from a simple DC-DC boost converter to a multi-phase interleaved DC-DC boost converter with an arbitrary number of legs. Both static and dynamic state-feedback pole placement control laws are considered.

DCM operation of interleaved DC/DC converters for PV applications
2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012In this paper the interleaved operation of boost converters employed in a photovoltaic power processing system is proposed. By forcing the converters to work in discontinuous conduction mode, an high voltage conversion ratio and a significant noise rejection capability are obtained.

Research on Interleaved Bidirectional DC/DC Converter
2016Interleaved bidirectional DC/DC converter uses interlaced structure and carrier phase-shifted method, which achieves better performance at a lower current ripple and more stable output voltage characteristics as well as high energy density. In this research, the structure of the two-channel topology with phase-shifting of 180° is introduced, which ...

An Active Snubber Cell for -Phase Interleaved DC–DC Converters
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2014An active snubber cell and its dual circuit for reducing switching losses of 1 to N phase dc-dc converters is presented. Main switch(s) of the converter can be turned-on and - off at zero-voltage (ZV); auxiliary switch of the proposed snubber cell can be turned-on at zero-current (ZC) and turned-off at ZV.

Interleaving optimization in synchronous rectified DC/DC converters
2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004Interleaving in synchronous rectifiers can lead to reduced losses in both the active and passive components. However, this depends on selecting the correct number of phases and the correct phase inductance for a particular application and requirements. In this paper optimizing the number of phases and the phase inductance is considered to maximize the ...

Research on a Novel Interleaved Flyback DC/DC Converter
2006 1ST IEEE Conference on Industrial Electronics and Applications, 2006Flyback converter has been widely used in low-power applications because of its relative simplicity when compared with other topologies. This paper proposes a novel interleaved flyback DC/DC converter, which provides the additional benefit of recycling transformer leakage inductance energy and reducing voltage stress of the power switches.

Decentralized interleaving of paralleled dc-dc buck converters
2017 IEEE 18th Workshop on Control and Modeling for Power Electronics (COMPEL), 2017We present a decentralized control strategy that yields switch interleaving among parallel-connected dc-dc buck converters. The proposed method is based on the digital implementation of the dynamics of a nonlinear oscillator circuit as the controller. Each controller is fully decentralized, i.e., it only requires the locally measured output current to ...
