“…Nevertheless, the ZVS/ZCS operation reduces switching losses significantly, which leads to increase the converter efficiency. Some topologies like Nouri et al 26,29 perform higher BF than the proposed topology. However, they need more elements than the proposed converter.…”

A new step-up dc-dc converter with the interleaved operation is proposed. This converter is equipped with a novel active clamp circuit that provides zero-voltage switching (ZVS) operation for power switches and zero-current switching (ZCS) for diodes. High-efficiency, interleaved structure, common-ground, and continuous input current are other features of this topology. Also, the presented topology provides higher boost factors due to using coupled inductors. Therefore, this topology is useful for connecting to renewable energy resources like photovoltaic panels and fuel cells. Due to its soft-switching operation and high efficiency, this converter can be designed for high-power applications. As a result, this converter can be utilized in stand-alone electric vehicle charging stations. Simulation and experimental results are presented to evaluate this topology. For this purpose, a 48-V/380-V/500-W prototype has been built. Results confirm the above claims.

“…A more symmetric four-phase inverse coupled inductor structure, in order to substantially improve the multiphase interleaved bidirectional buck/boost converter, is presented in [20] and provides high efficiency in both modes with lower voltage ripples. An optimized design process of high power multi-phase interleaved bidirectional boost converters is presented in [21], in order to achieve a fast and accurate analysis and design for electrified power trains. Hence, the converters in [18][19][20][21] are suited for high power rating as well as high efficiency measurements.…”

A modified Topology to acquire high efficiency of a bidirectional method of DC–DC converter of non-isolated approach is proposed. The modified circuit involves four numbers of switches with their body diodes, passive elements as two inductors as well as a capacitor and the circuit arrangements double boost converters to progress the voltage gain. The input current of the proposed topology divided amongst the two dissimilar values of inductors produces greater efficiency. In the step-down mode, an apparent lessening in voltage gain and also enhanced efficiency can be realized in the recommended system by expending a synchronous rectification. The modified topology shields the technique for presentation of easy control configurations and is used for truncated output voltage with a large current of energy storage systems in the renewable applications as well as hybrid energy source electric vehicle applications. The simulation of the projected structure has been conducted through MATLAB/Simulink software and has been corroborated through a 12 V/180 V, 200 Watts experimental prototype circuit.

A new high efficiency interleaved pulse‐width modulation (HE‐IPWM) method using parallel‐connected Mosfets is presented. The IPWM is evaluated using a bidirectional DC‐DC converter for charging and discharging a battery. The results show an excellent DC voltage gain without an extremely large duty cycle. Compared with conventional pulse‐width modulation (CPWM), the IPWM reduces by half the ripple of the battery current. The current ripple of IPWM is four times higher of the switching frequency, while CPWM is two times higher. The proposed interleaved strategy also double the inductor current ripple frequency, whereas in general, is equal to the switching frequency. As a result, the use of the IPWM reduces the weight and size of inductor design. Furthermore, IPWM provides the best battery current ripple at the duty cycle close to 25%. The operating stage, mathematical analyses, and design guidelines of the two proposed modulations are explained in detail. The IPWM experimental results of a 250‐W prototype confirmed the circuit performance. The maximum efficiency of 98.9% is obtained at 250 W for boost mode and 99% for buck mode.
