“…The equations used to dimension the power elements in a buck converter are described in Reference [50] and are presented in (10) and (11). While the equations used for the sizing of the power elements in a boost converter are described in Reference [51] and are presented in (12) and (13).…”

“…Moreover, the input inductors are operated in discontinuous conduction mode; thus, power can be shared between input sources through proper selection of input inductors. In Reference [12] a new modified LCLC series resonant circuit based dual-input single-output isolated converter is proposed for hybrid energy systems. With this novel converter topology, two different voltage sources can be decoupled completely and transfer the power from two separate dc sources to dc load simultaneously.…”

Electric Vehicles (EVs) are an alternative to internal combustion engine cars to reduce the environmental impact of transportation. It is common to use several power sources to achieve the requirements of the electric motor. A proper power converter and an accurate control strategy need to be utilized to take advantage of the characteristics of every source. In this paper is presented a novel topology of a multiple-input bidirectional DC-DC power converter to interface two or more sources of energy with different voltage levels. Furthermore, it can be used as a buck or a boost in any of the possible conversion of energy. It is also possible to independently control the extracted power in each source and any combination of the elements of the system can be used as source and destiny for a transfer. Finally, the interaction with the grid is possible. The operation, analysis and design of the converter are presented with different modes of power transfer. Simulation results are shown where the theoretical analysis of the converter is validated.

“…The isolated TPC uses a transformer with a high-frequency nonisolated converter topologies. The isolated TPC uses a transformer with a high-frequency to provide magnetic coupling and electrical isolation between the source and load [6][7][8]; partially isolated converters use a common DC bus along with magnetic coupling [9]. A nonisolated TPC uses common DC bus and finds applications where the isolation is not needed between the ports [10][11][12].…”

A nonisolated three-port DC–DC converter based on Cuk topology (NI-TPC) to handle the renewable sources (RS) is proposed in this paper. This converter includes two unidirectional input ports accommodating both a fuel cell (FC) and photovoltaic (PV) cell; and one output port with DC load. Due to the inductors at all the ports, it claims the advantage of continuous input and output currents. Additionally, it uses less number of switches, diodes and inductors compared with conventional ‘n-1’ separate Cuk converters. Synthesis procedure for a generalized n-port DC–DC structure is explained. The derivation law based on conventional Cuk converter, operating principle, design calculation, and analysis are presented in detail, and then the analysis is validated through simulation and a 100W prototype, verifying the performance of the proposed NI-TPC converter.

“…Such a DIC will malfunction in case that either of the two inputs fails. The parallel-type DICs collocate different sources in parallel so that even if one of the inputs is out of commitment, it still can accomplish voltage stepping to meet DC-bus level [17][18][19][20][21][22][23]. Some of them are controlled with time-sharing scheme.…”

A dual-input high step-up isolated converter (DHSIC) is proposed in this paper, which incorporates Sheppard Taylor circuit into power stage design so as to step up voltage gain. In addition, the main circuit adopts boosting capacitors and switched capacitors, based on which the converter voltage gain can further be improved significantly. Since the proposed converter possesses an inherently ultra-high step-up feature, it is capable of processing low input voltages. The DHSIC also has the important features of leakage energy recycling, switch voltage clamping, and continuous input-current obtaining. These characteristics advantage converter efficiency and benefit the DHSIC for high power applications. The structure of the proposed converter is concise. That is, it can lower cost and simplifies control approach. The operation principle and theoretical derivation of the proposed converter are discussed thoroughly in this paper. Simulations and hardware implementation are carried out to verify the correctness of theoretical analysis and to validate feasibility of the converter as well.
