   A New Nine-switch Non-regenerative Four-level Rectifier
By XIBO YUAN [View]
[Download]

Abstract: This paper has proposed a new non-regenerative three-phase four-level rectifier topology with only half of the active devices of the conventional four-level rectifier. Each phase leg has only three active devices. The operation of the rectifier with regards to current path and output voltage levels are analysed. The available voltage vectors in this type of rectifier are constrained by the current flow direction. The maximum active power and reactive power capacity of the rectifier have been derived. A simple carrier-based modulation scheme is presented to modulate the rectifier as well as balance the dc-link capacitors voltages. Simulation results have validated the topology and control scheme.

   Design considerations for a contactless battery charger

Abstract: Contactless power transfer using inductive coupling is a well-known way to transfer energy from a transmitter to a receiver without any physical link. The applications are multiple. In this paper, the design and control of such a system for a contactless battery charger is investigated. The behaviour of the battery turns the system into a non-linear one. A solution dealing with the compensation topologies which aims to simplify the control of the transformer without any additional power electronics is proposed.

   Large Input-Voltage Range DC-DC Converter for High-Efficiency PV Applications
By Pedro BANUELOS-SANCHEZ, Jacobo AGUILLON-GARCIA [View]
[Download]

Abstract: It is known that, the energy extracted from photovoltaic (PV) panels oscillates in magnitude during the light-day interval. In addition, an ideal location of PV systems involves the awareness of solar supply characteristics in order to establish a better use of this resource. In the solar energy systems this solar irradiance variation is partially engaged, limiting the converters transformation rate for a certain input amount and leaving the rest of energy unconverted. This lends a restricted use of photovoltaic panels energy capability. In order to utilize at its maximum the energy provided from a PV system, this manuscript proposes a topology that can cope with marginal input voltage variations from 60VDC up to 1050VDC for a steady output voltage of 700VDC. This output voltage value is suitable for any interlink post-regulation architecture. Based on previous observations, this paper presents a wide-input voltage high-efficiency non-isolated single-control topology. Analysis, operating stages and experimental results for a 3kW prototype are presented.

   Multi-Port Converter with bidirectional energy flow for automotive energy net applications
By Markus SIMON, Michael MUERKEN, Christian AUGUSTIN, Johannes PFORR [View]
[Download]

Abstract: A novel family of multi-port converters with bidirectional energy flow has been investigated for lowvoltagehigh-current automotive energy-net applications. An example is given of a three-portconverter designed for the 14 V/42 V automotive energy net and providing the possibility to alsoconnect a double-layer capacitor to relieve the battery from excessive current stress and to stabilize theenergy net voltages. The proposed three-port converter requires only three MOSFETS as switchingdevices. Analyses have been performed to investigate the suitability of the multi-port converter for thegiven application and a prototype converter has been built and tested to prove theoretical predictions.Measurements are in good correlations with results from the analysis.
