The proposed dual input hybrid buck C/hybrid buck L (HBCL) DC-DC converter, is suitable for power conversion in renewable energy, automotive and telecom power systems. It extends the use of the hybrid DC-DC converters in a dual-input structure, with high voltage-conversion ratio. Operation modes, analytical description, digital simulations and test results, in good correspondence, are presented and discussed in this paper.

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...
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...
A Fully Integrated Power Management Circuit for Electromagnetic Energy Harvesting Applications Gharehbaghi, Kaveh; Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2012-12-05) In this paper a 90 nm power management circuit for vibration based electromagnetic energy harvesters is introduced to generate 1 V from the rectified DC voltage. A mode selector block is designed to detect the output DC voltage level of the rectifier and adjust the mode of the driver block. In order to set the output to the desired level, a regulation system with negative feedback topology is utilized. The circuit is able to operate with input voltages as low as 0.25 V. The simulation results also show that...
Modeling and Control of Interleaved Multiple-Input Power Converter for Fuel Cell Hybrid Electric Vehicles Hegazy, Omar; Van Mierlo, Joeri; Lataire, Philippe (2011-09-10) 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 pro...
Design of a Power Plant Emulator for the Dynamic Frequency Stability Studies Duymaz, Erencan; Pourkeivannour, Siamak; Ceylan, Doğa; ŞAHİN, İLKER; Keysan, Ozan (2018-10-25) Increasing renewable energy integration to grid requires inertial support to improve frequency stability of the power system. Inertial support of renewable energy systems requires hardware verification in order to test practical limitations and absence of dynamical grid simulators makes verification studies more challenging. In this study, a test rig which is composed of a DC motor, an AC synchronous generator and an external flywheel, is developed in order to provide a platform in which dynamic properties ...
