“…So, considering Table 6, the values of used capacitors for parameters as r C1 = r C2 = r C3 = 0.05 Ω, R o1 = 700 Ω, R o2 = 1400 Ω, D 1 = 35.5%, D 2 = 30% and f s = 30 kHz are approximately calculated as C 1_min ≃ 40 μF, C 2_min ≃ 20 μF and C 3_min ≃ 2 μF. Moreover, considering (27) and (28), the inductances L 1 and L 2 to achieve CCM operation of the proposed converter are Table 6.…”

In this study, a new DC-DC single-input-dual-output (SIDO) converter is proposed which is able to step up and share the input voltage between the output terminals with constant duty cycle for whole ranges of duty cycles. Due to the fact that the voltage stresses on the semiconductors of the proposed converter are considerably low, the proposed converter can be applied in both low-and high-power applications. This topology can be used instead of two boost converters, which have very improved conversion ratios in comparison with the recently presented step-up converters. The proposed configuration can be used in many applications such as renewable energy sources and diode-clamped inverter in the grid-tied systems. In this paper, steadystate and small-signal analyses of the SIDO converter are presented and the simulation and experimental results are extracted and compared. In practical applications that SIDO is needed, using single-input-single-output can be a solution, resulting high cost. To reduce the costs, this study proposes a novel topology, which has reduced components and can step up the input voltage into two separate ports. Finally, a prototype circuit with 42 V input and 510 V/372 W and 730 V/381 W outputs are built to validate the theoretical analysis.

“…22 indicates the measured efficiency of the DOSI system based on the proposed approach. The peak efficiency is 91.7%, which is similar to [20,21] (91.3, 92%), a little higher than [22][23][24][25] (91, 89, 88, and 87%), and a little lower than [26] (93.5%). The feasibility of the multi-bus motor drive system and control method has been validated experimentally, as presented in Figs.…”

“…The DOSI structure has advantages in having fewer circuit elements and conversion stages, which will result in both a lower cost and a more compact size compared with other structures with several independent single-inductor-single-output converters [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Despite its merits on cost and a simpler structure, the singleinductor-dual-output circuit suffers in handling load variations, especially for highly dynamic loads such as electric motor loads, since the DOSI structure has been typically used for low-power integrated circuits [10][11][12][13][14][15][16][17][22][23][24].…”

48 V electric system architecture has been recently introduced to accommodate an increasing number of electric components in mild hybrid electric vehicles. In this study, two additional DC buses are added for electric machines including 36 and 24 V AC-and DC-motor/actuator loads, in a 48/12 V power supply system. This structure can yield significant benefits, especially for electrified vehicles that have more electric machines and actuators. A single-inductor multi-output structure is employed, with a control strategy that produces linear transfer functions and is less sensitive to load variation, to accommodate multiple-bus motor/actuator drives. The proposed structure and control strategy can offer options for selecting proper bus voltages, optimising the electric machine's power density. Both simulations and experiments have been performed to verify the system structure and control schemes using 36 and 24 V electric machines connected to the additional dual-output buses on top of the existing 12/48 V bus structure.

“…Such a converter not only can interface two storage systems with the DC link using a reduced number of switches, but it allows also a higher conversion efficiency. Indeed, on the one hand, reducing the number of switches in multi-input or multi-output converters is a topic of great interest in the technical literature [36][37][38][39], on the other, DC-DC converter efficiency is a key point in hybrid vehicles. In [32], a conduction loss comparison between the traditional four-switch converter (4SC) and the innovative three-switch converter (3SC) is carried out; however, regarding switching losses, only a qualitative study was performed.…”

A Refined Loss Evaluation of a Three-Switch Double Input DC-DC Converter for Hybrid Vehicle Applications

In this paper, an accurate efficiency evaluation of an innovative three-switch double input DC–DC converter for hybrid vehicle applications was carried out. The converter was used to interface two storages, (e.g., supercapacitor and battery) to the DC link. A refined model was created in MATLAB/Simulink Plecs environment and it was used to compare the traditional four-switch converter (i.e., two DC–DC converters in parallel connection) with the innovative three-switch converter. Loss and efficiency contour maps were obtained for both converters and a comparison between them was performed. A prototype of the three-switch converter was realized and used to validate the simulation thermal model by comparing both efficiency and current waveforms obtained with simulations and experimental tests.
