This paper proposes a new nonisolated multiport DC-DC converter with two inputs and two outputs with different voltage levels. Different energy sources with distinct voltage-current characteristics can be utilized as the input sources. Regarding multiple outputs, the proposed converter can be utilized in electric vehicles (EVs) to supply the DC traction motor and the auxiliary loads. The main advantages of the proposed converter include the high voltage gainwith small values of the duty cycles, low normalized peak voltage stress (NPVS) across the semiconductors, and the continuous input currents. The voltage stress across the semiconductors is lower than the maximum output voltage. This feature makes it possible to use the switches with low turn-on resistance and the diodes with reduced rating voltage. Performance principals of the proposed converter along with the steady-state analysis, such as the derivation of the voltage gains, voltage and current stresses of the semiconductors, etc, are carried out. Experimental measurements made for the laboratory prototype of the proposed converter confirm the theoretical analysis. ;48:934-952.wileyonlinelibrary.com/journal/cta microelectronics, hybrid/electric vehicles, and lighting that includes electronic ballast and light-emitting diodes. 6 Regarding the abovementioned subjects, multi-input-multioutput (MIMO) DC-DC converters are employed in various applications. In Zhou et al, 7 a high step-up multiport DC-DC converter has been presented. Low voltage stress on the switches is the main feature of this structure. However, the voltage stress across the diode in one of the boost cells is equal to the output voltage. Furthermore, n inductors and n switches are needed for n-input single-output case, which causes the converter costs to be high. The converter in Deihimi et al 8 can provide higher voltage gains by increasing the number of inputs. However, the number of switches and inductors is increased, which in turn increases the cost and weight of the converter. The buck-boost and boost-based converter presented in Banaei et al 9 is capable of generating a high voltage gain. However, the output switch and diode experience high voltage stresses that limit its application. To have n-input in this converter, n inductors and n switches are required, which cause extra costs, big size, and high losses. A high step-up noncoupled inductor-based multiport DC-DC converter with reduced normalized peak voltage stress (NPVS) across the semiconductors has been presented in Varesi et al. 10 The modularity and continuous input currents are the other advantages of this converter. A two-phase high step-up DC-DC converter with reduced voltage stress across the switches and diodes has been presented in Hwu and Jiang. 11 The switched-capacitor-diode technique is applied to the conventional boost converter to increase the voltage gain in Hou et al. 12 A single-pole switch leg-based converter with three output ports and one bidirectional battery port has been presented by Kim and Kwak. 13 Saad...

Considering (19) and (20), the voltage conversion ratio between V ℓ and V H1 depends only on the duty cycle of D 1 and the voltage conversion ratio between V ℓ and V H2 depends on both duty cycles…”

In this study, a non-isolated three-port high step-up/step-down DC-DC converter is proposed. The proposed converter has the capability of cancelling the input current ripple in the high current port, moreover, the voltage conversion ratios between the high voltage and low voltage are increased by coupled inductors. All the ports of the proposed converter have a common ground. In addition, any of the three ports can be used as an input voltage source, which can supply the other two ports. The number of DC voltage ports of the proposed converter can be more increased by using more inductor-switch cells. In this study, the theoretical results of the proposed converter are obtained and the voltage conversion ratios of the output ports, the voltage and current stress on switches, average currents of inductors, and the required condition of cancelling input current ripple at the low voltage side are calculated for the proposed three-port converter. The voltage gains of the developed converter with four ports are also calculated. Finally, the theoretical results are reconfirmed by the experimental results for 28 V input/150 and 460 V output ports.

“…Conversely, non‐isolated topologies are based on the use of techniques to increase the voltage gain [7], such as coupled inductors [8, 9], switched‐inductors (SLs) [2, 10, 11], switched‐capacitors (SCs) [10, 12, 13], stacked [14] and cascaded [15–17] connection. Clearly, the converters based on these techniques also present some disadvantages [10] such as voltage spikes on the switches (coupled‐inductor and SL) and a high number of components (SC, stacked and cascaded converter) [10].…”
