“…Due to its high efficiency and controllability, the PMBLDC motor is the most popular option in the drive train of low-to-medium power EVs. In the past decade, to improve the drivetrain's efficiency, research on bidirectional DC-to-DC converters (BDCs) for EV applications has been extensively done [1][2][3][4][5]. e problem with these BDCs is that they have a large number of component requirements and high voltage stress on the switches.…”

In this study, a bidirectional DC-to-DC quadratic converter (BDQC) is designed and developed for the motoring and regenerative braking (RB) of a permanent magnet brushless DC (PMBLDC) motor for a light electric vehicle (LEV) application. A PMBLDC motor is deemed more suitable for an electric vehicle (EV) due to its high efficiency and torque density. In the present work, a BDQC of 1 kW is designed to drive a 1.1 HP PMBLDC motor through a conventional voltage source inverter (VSI). An EV’s load cycle is emulated using a highly inertial load driven by a PMBLDC motor during the converter’s boost mode operation. RB is a crucial factor in extending the driving range of EVs by efficiently utilizing battery power. The converter operates in buck mode during RB, and simultaneously, the back electromotive force (EMF) of the PMBLDC machine is boosted by the self-inductance of the PMBLDC motor and the VSI. The braking technique used in this work eliminates the traditional drawback of RB in buck mode, as the power is extracted even when the motor’s back EMF is lower than the battery’s voltage. The control strategy has been implemented using the TMS320F28335 DSP controller for a developed converter prototype of the converter and driving the PMBLDC motor. The experimental results are compared to the simulation results, and a good alignment has been found.

“…To achieve a wide voltage conversion ratio, converter configurations make use of multiple passive components within fairly complex circuits [10][11][12][13][14][15][16], multilevel structures [17][18][19], switched capacitor or inductor cells in hybrid [20,21] or extendable structures [22][23][24][25][26], or even multiple cascaded converters [27]. A disadvantage of these converters is that the larger number of passive components results in an increase in the complexity of control and reduction of the power density of the system, as presented in [20,28].…”

A bidirectional hybrid switched inductor converter (BHSI) is proposed in this paper. The converter uses an inductor switching cell in order to achieve a wide voltage conversion range, smaller passive components, and lower stress on the active devices. Apart from these advantages, the introduction of the additional inductor in the switching cell does not increase the complexity of the control structure, as is usually the case with other topologies with multiple components. The BHSI is compared, in terms of inductor/capacitor energies and total device stress, to other state-of-the-art topologies and its advantages are highlighted. Two 3 kW prototypes were built, using Si-MOSFETs and GaN-FETs, in order to analyse their performances from the efficiency point of view, and to validate the theoretical findings. The stability analysis of the converter is performed and tested in a supercapacitor storage application, resulting in a good operation in both charge and discharge modes.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Berrehil et al 6 presented an isolated three‐phase bidirectional DC–DC converter connected to the DC microgrid system in which efficient power conversion with a wide input voltage range and continuous input current could be achieved. However, when the turns ratio is too high, the transformer linearity will be affected, and leakage inductance of the transformer will be increased 7 . Therefore, nonisolated DC–DC converter has received extensive attention due to its characteristics of excellent performance and high power density 8 …”

Summary As a kind of new energy power generation technology in the 21st century, hydrogen fuel cell plays an indispensable role in energy network. However, due to its characteristics of low output voltage and large fluctuation, direct current–direct current (DC–DC) converter with high step‐up voltage gain has become a key part for safe and stable operation of fuel cell. In this paper, by replacing the inductors on the input side of interleaved boost converter with switched‐inductor units (small current ripple) and adding a capacitor–diode unit with strong voltage multiplication to the output side, an innovative interleaved high step‐up DC–DC converter is proposed with high step‐up voltage gain, small inductor current, and low voltage/current stresses. In addition, working principle, steady‐state performance, device parameter design, and theoretical efficiency calculation for the entire duty cycle range (duty cycle D < 0.5 and D > 0.5) are carried out, respectively, to verify its validity and feasibility. Finally, a 150‐W experimental prototype of fuel cell front‐stage power conversion is established. When the input voltage and output current are 16 V and 1.25 A, respectively, the efficiency of the entire system can reach about 92.6%.
