Interleaving techniques are widely used to reduce input/output ripples, to increase the efficiency and to increase the power capacity of the DC/DC converters. This paper proposes an interleaved multiple-input power converter (IMIPC) that interfaces the fuel cell and energy storage systems (e.g. Batteries or/and Supercapacitors) to the powertrain of the hybrid electric vehicles. The IMIPC is responsible for the power-flow management on-board vehicle for each operating mode. In this research, the IMIPC is proposed in order to reduce the input current ripples, to reduce the output voltage ripples and to reduce the size of passive components with high efficiency. In addition, low EMI and low stress in the switches are expected. Moreover, a generalized small signal model of the IMIPC is derived in order to design the closed-loop control strategies. The proposed power electronics interface (PEI) and its controller are designed and analyzed by using Matlab/Simulink The simulation results have demonstrated that the proposed power electronics interface achieves a high performance for high power converter and it can be applied in the FCHEVs.

Operating principles and practical design aspects of all SiC DC/AC/DC converter for MPPT in grid-connected PV supplies ÖZTÜRK, SERKAN; Popos, Polat; Utalay, Volkan; Koc, Atila; Ermiş, Muammer; ÇADIRCI, IŞIK (2018-12-01) A 20 kW, 20 kHz high frequency (HF) link maximum power point tracking (MPPT) converter for a grid-connected PV supply, based on all silicon carbide (SiC) power semiconductors, is presented. In the developed converter, SiC power MOSFETs are used in the low-voltage PV panel side and SiC Schottky diodes on the high-voltage DC output, in order to maximize the power conversion efficiency and the power density. Operating principles of the resulting dual H-bridge MPPT converter and the practical aspects of the con...
Efficient integrated DC-DC converters for ultra-low voltage energy harvesters Jayaweera, Herath; Muhtaroğlu, Ali; Sustainable Environment and Energy Systems (2017-8) The self-starting on-chip fully integrated ultra-low voltage DC-DC converters for energy harvesting applications presented in literature generally have low efficiency and output power capacity. Any improvement in DC-DC converter circuits in terms of energy efficiency, output power, self-starting modes, and voltage gain will contribute significantly to the widespread application of energy harvesters. Two novel fully integrated, self-starting, ultra-low voltage DC-DC converter topologies and model based optim...
Optimal Design of Grid-Connected Voltage-Source Converters Considering Cost and Operating Factors Kantar, Emre; Hava, Ahmet Masum (2016-09-01) This paper assesses the feasibility of three-phase pulse-width modulated (PWM) three-level voltage-source converters (VSC), namely neutral-point-clamped (3L-NPC) and T-type (3L-T) as alternatives to two-level converter (2L-VSC) for low-voltage multimegawatt renewable energy grid-connected converter applications. For this purpose, a novel design algorithm that takes switching frequency, capacity factor, modulation index, PWM scheme(s), and converter topology(ies) as input is unveiled to provide the design st...
Performance evaluation and comparison of low voltage grid-tied three-phase AC/DC converter configurations with SI and SIC semiconductor switches Öztoprak, Oğuzhan; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2019) In this thesis, as compared to silicon IGBT (Si-IGBT) technology, the advantages of using higher efficiency and faster wide bandgap silicon carbide (SiC) semiconductor switches in low voltage three-phase grid-tied PWM DC/AC voltage source converters (VSCs) are investigated in terms of sizing, efficiency and economic considerations for MW-scale photovoltaic power plant applications. As the cost and energy efficiency of a VSC strongly affect the total system economics, this thesis proposes a design methodolog...
Active clamped ZVS forward converter with soft-switched synchronous rectifier for maximum efficiency operation Acik, A; Cadirci, I (1998-05-22) An active-clamped, zero-voltage switched forward converter equipped with a soft-switched synchronous rectifier is designed and implemented for some low output voltage applications where maximized efficiency is of utmost importance. The converter efficiency is maximized due to soft-switching of the main, active clamp and the synchronous rectifier MOSFET switches. Experimental results are presented for a converter with a de input voltage of 48V, an output voltage of 5V and a de electronic load up to 10A. The ...
