   A Versatile Low Power Test Bench for Induction Metal Heating
By Houcine ZEROUG, Amar OUZOU, Amine OULEBSIR, Billel MEZIANE, Nadia TADRIST [View]
[Download]

Abstract: In this paper, a focus is made on design of a test bench resonant inverters for induction heating for industrial applications like metal heat treating. The design is based on half and full bridge single phase inverter of 1 and 4 kW rating. First, the power circuits of the two topologies are analyzed using computer aided design based on Simplorer package. Then, a small scale experimental system was built and tested using microcontroller chip. The performances of the topologies are highlighted and assessed. The obtained results show that two systems are able to operate satisfactory under soft switching at high frequency with high efficiency. The power control is more interesting for full bridge particularly when the angle phase control is considered. Further, the experimental results agree well with those obtained with the CAD design in the low power range. This validates the design model used for the purpose. Then, the model is exploited further for to develop a high power application.

Abstract: The paper presents a design of a 2kW Resonant Power Supply dedicated for telecom applications. The power supply is based on a series-parallel LCLC resonant converter, which has some interesting features, such as self protection from load short-circuit. The design comprises an integrated magnetic component intended to be used as the resonant tank inductors. The construction presented in the paper allows for reduction of the size of the inductors and improves the magnetic core utilization. The paper explains the principle of operation of the integrated magnetic component, followed by functional and magnetic field simulations. Measurement results are presented for final verification.

Abstract: In power electronic converters soft switching is an efficient way to reduce losses. A resonant tank in series with the windings of the isolation transformer in aModular Double-Cascade converter is presented. Positive effects such as switching loss reduction, prevention of flux walking and saturation of transformer core are analyzed and discussed.

Abstract: This paper presents a new parametric model of a single-active-bridge (SAB) converter with a variablenumber of phases. The soft-switching behavior and the design of snubbers are also analyzed. Theanalytical study is validated using PLECS simulation software and a configurable 10kW/ 20 kHz / 500Vexperimental prototype.

   Reduction of Switching Losses in Bidirectional DC/DC Converters for Automotive Use
By Tim ENDRES, Jens SCHROEDER, Friedrich FUCHS [View]
[Download]

Abstract: This paper describes a novel way to implement soft switching into DC/DC converters for high current low voltage applications in the automotive field. Adding resonant elements to a bidirectional buck boost converter enables resonant behaviour. In simulation and laboratory measurement it is shown that this behaviour reduces the switch-off losses strongly.

   SiC Multi-inverter frequency band division design for increased flexibility in an induction heating surface area
By Javier AVELLANED, Carlos BERNAL, Pilar MOLINA [View]
[Download]

Abstract: This paper presents a simple solution to combine three one-switch inverters in a cell sharing one EMIfilter and avoiding the appearance of audible intermodulation distortion. The concept is based on makingthe designs asymmetric thus distributing in different frequency bands the switching frequencies. Withsome previous analysis to support the selection of these frequencies, no audible noise appears. Thisconcept has been tested experimentally with results showing good agreement with predicted ones.

   Soft-Switched, Transformerless Inverter Suitable for Photovoltaic Panels
By Ilija PECELJ, J.A. FERREIRA, Sjoerd DE HAAN [View]
[Download]

Abstract: A novel, soft-switched, transformerless, DC to AC inverter, suitable for direct connection ofphotovoltaic (PV) panels is presented. The proposed topology features indirect energy transfer bymeans of a resonant AC link. This enables grounding of the DC side of the inverter, which isbeneficial in PV installations. Operation of the proposed inverter is described and verified bysimulations. Experimental prototype is constructed, and preliminary measurement results arepresented.

   Zero Voltage Switching configuration of a dual inductor current fed DC/DC converter
By Luigi PIEGARI, Enrico TIRONI, Sergio TOSCANI [View]
[Download]

Abstract: In recent years, DC/DC converters have become more and more widespread due to the development of new DC energy sources. This has led to intensive studies of DC/DC converters and new configurations have been proposed in the literature. In particular, there are very interesting high efficiency configurations. The current fed, DC/DC push-pull converter with two input inductances was thoroughly analyzed because it can achieve a high ratio between its input and output voltages and intrinsic insulation. In particular, a modification of the standard converter is proposed. The studied configuration makes ZVS operations possible and increases the efficiency of the system. This paper proposes the new configuration and reports its working principles in detail. A case study is numerically simulated. The results show the ZVS operation, with an increase in the global efficiency.
