A multiport converter promises cost-effective, flexible and more efficient energy processing by utilizing only a single power stage. Multiport converters, a promising concept for alternative energy systems, have attracted increasing research interest recently. Zero Voltage Switching (ZVS) alleviates the switching losses and improves the converter overall efficiency. Zero voltage switching can b...

In distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. In this paper, the Hybrid Shuffled Frog Leaping Algorithm (HSFLA) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. High accuracy and ...

In this paper, an interleaved soft switching boost converter for a Photovoltaic Power Conditioning System (PV-PCS) with high efficiency is proposed. In order to raise the efficiency of the proposed converter, a 2-phase interleaved boost converter integrated with soft switching cells is used. All of the switching devices in the proposed converter achieve zero current switching (ZCS) or zero volt...

In this work a buck converter model for multidomain simulations is proposed and compared with a stateof-the-art buck converter model. In the proposed model no switching events are calculated. By avoiding the computation of the switching events in power electronic models the processing time of multi-domain simulations can be decreased significantly. The proposed model calculates any operation po...

Zero-current-transition, discontinuousconduction-mode (ZCT-DCM) converters are introduced in this paper. Compared to hard-switching (PWM) converters in DCM, the ZCT-DCM converters have similar current stresses and conduction losses, and much reduced turn-off switching losses. At the expense of increased voltage stresses, zerocurrent/zero-voltage switching is maintained for a wide range of loads...
