“…A number of topologies are proposed in the literature [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] to transfer the power from one source to another in hybrid electric vehicle (HEV) and microgrid applications. In [17], multiple sources are interfaced using a common high-frequency transformer, where each source is connected through full-bridge cells utilizing twelve switches for three sources.…”

“…In this topology, it is not possible to transfer energy directly between dc sources and also a higher number of devices are being used. Multiple bidirectional boost converters are connected in parallel to interface multiple dc sources with its output connected to common dc link to supply the inverter [23][24][25][26][27]. Voltage levels of the auxiliary sources are limited to below the dc link voltage because it can only boost the input voltages.…”

This paper proposes a novel multiple-input bidirectional DC-DC power converter to interface more than two dc sources of different voltage levels. This finds applications in hybrid electric/fuel cell vehicles, where different dc sources of unequal voltage levels need to be connected with bidirectional power flow capability. Converter can be used to operate in both the buck and boost modes with bidirectional power control. It is also possible to independently control power flow between any two sources when more than two sources are actively transferring power in either direction. The operation, analysis and design of the converter are presented with different modes of power transfer. Proposed converter is demonstrated for fuel cell vehicle application using real-time hardware-in-the-loop system. Experimental results for a 5kW system are presented validating the theoretical analysis.

Failure of power electronic systems plays a substantial role in the breakdown of hybrid vehicle electric drive systems. Early detection of faults can avoid aggregation of the failure and prevent catastrophic consequences. The aim of this paper is to test the sensitivity of statistical moments on power semiconductor faults in a bidirectional DC/DC converter interfacing the main hybrid energy storage system and the electric drive system in hybrid electric vehicles. Time domain analysis of current and voltage signals obtained from sensors at the input/output terminals of the converter is used to detect system faults in the power converter system.

“…The non-isolated topologies usually connect several basic converters in parallel at the input side. For example, [2] [3] connected several boost converters at the input side, [4] [5] connected several buck converters at the input side, [6] [7] utilized several buck boost converters, and [8] [9] utilized several Z-source converters. There are also some work combining different basic converters together to form the multiple-input converter [10] [11].…”

In this paper, a dual-input full-bridge currentsource isolated dc/dc converter is proposed to combine the Photovoltaic (PV) system with the Energy Storage System (ESS). The proposed converter utilizes a full-bridge as the primary side, and the Quasi-Switched-Capacitor circuit as the secondary side. Compared to other multiple-input dc/dc converters with galvanic isolation function, the proposed converter utilizes less number of switches and passive components, reduces voltage stress on switches, and can achieve a high efficiency at a high switching frequency. The operation principle of the converter is presented, and a power sharing strategy between two input sources is proposed. A 2.0 kW, 1 MHz, 40 V/ 400 V prototype utilizing Gallium Nitride (GaN) switching devices is built in the lab, and experimental results show that a peak efficiency of 95.9% is achieved at 500 kHz.
