“…Due to this feature, the SAHVC can function properly at high switching frequencies with minimal switching losses while maintaining a high-power density. Moreover, isolated-MPC is the best-suited candidate in BEVs and PHEVs because it reduces input current ripples and output voltage ripples, minimizes the size of passive components, improves efficiency and having high power handling capability [47][48][49][50][51][52][53].…”

“…Thus, the interleaving technique allows the input inductor size and output capacitor size to be reduced. The frequency of the input current ripples is N times higher than the switching frequency f sw because the control signals are interleaved and have a phase angle of 360 • /N [52][53][54][55]. As a result, input current ripple and output voltage ripples lessen which is the best reason to choose this converter topology for BEV and PHEV powertrains.…”

“…An argument could be made for using a transformer to step-up the output AC voltage level instead of using a DC-DC converter. However, the advantages of using the DC-DC converter is that it is lightweight, compact in size, low-priced, highly efficient and reliable [52]. Moreover, an HV battery can be used instead of an HV DC-DC converter with a complex battery management system (BMS).…”

This article reviews the design and evaluation of different DC-DC converter topologies for Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs). The design and evaluation of these converter topologies are presented, analyzed and compared in terms of output power, component count, switching frequency, electromagnetic interference (EMI), losses, effectiveness, reliability and cost. This paper also evaluates the architecture, merits and demerits of converter topologies (AC-DC and DC-DC) for Fast Charging Stations (FCHARs). On the basis of this analysis, it has found that the Multidevice Interleaved DC-DC Bidirectional Converter (MDIBC) is the most suitable topology for high-power BEVs and PHEVs (> 10kW), thanks to its low input current ripples, low output voltage ripples, low electromagnetic interference, bidirectionality, high efficiency and high reliability. In contrast, for low-power electric vehicles (<10 kW), it is tough to recommend a single candidate that is the best in all possible aspects. However, the Sinusoidal Amplitude Converter, the Z-Source DC-DC converter and the boost DC-DC converter with resonant circuit are more suitable for low-power BEVs and PHEVs because of their soft switching, noise-free operation, low switching loss and high efficiency. Finally, this paper explores the opportunity of using wide band gap semiconductors (WBGSs) in DC-DC converters for BEVs, PHEVs and converters for FCHARs. Specifically, the future roadmap of research for WBGSs, modeling of emerging topologies and design techniques of the control system for BEV and PHEV powertrains are also presented in detail, which will certainly help researchers and solution engineers of automotive industries to select the suitable converter topology to achieve the growth of projected power density.

This study presents a symmetrical photovoltaic (PV)-connected inverter topology for eliminating the common-state leakage current in grid-connected inverters. A new inverter topology is introduced that minimizes the leakage current, increases efficiency, and is economically viable because it consists of six power switches and two power diodes that, compared with similar ones, consist of the same element numbers. In this inverter, power losses are lower than popular topologies such as H5, H6, and HERIC, and the voltage stresses of the switches are reduced. These features are due to the unique composition of the inverter branches and the location of the switches and diodes and the formation of a suitable freewheeling path for the current. The freewheeling path separates the alternating current (AC) side from the direct current side in the converter and cuts off the PV array leakage current to the AC grid. This will improve network reliability indices and maintain conservation standards. Finally, the content of this method is validated by comparing the proposed inverter with the existing conventional topologies. A prototype has been implemented for the performance analysis of the proposed inverter and results presented.

“…Contoh konverter lain yang digunakan adalah inverter satu fasa tipe jembatan yang dilengkapi dengan transformator untuk menaikan tegangan pada sisi luaran inverter [1] dan inverter boost satu fasa [6]. Kelebihan inverter boost satu fasa ini adalah tidak menggunakan transormator atau tambahan konverter lainnya untuk menaikan tegangan, sehingga lebih ekonomis untuk diimplementasikan [7][8]. Berdasarkan kelebihan dan kekurangan masing-masing konverter, maka dalam penelitian ini dipilih inverter boost satu fasa sebagai alat untuk menaikan sekaligus mengkon-versikan tegangan panel surya menjadi tegangan bolak balik sesuai dengan kebutuhan tegangan motor pompa air.…”

Pompa air tenaga surya adalah salah satu alternatif penyediaan air bersih untuk daerah yang belum terjangkau jaringan listrik. Pompa air tenaga surya membutuhkan peralatan yang dapat menaikan tegangan panel surya sesuai dengan rating tegangan motor pompa air dan inverter untuk mengkonversikan tegangan dc panel surya menjadi tegangan ac sesuai dengan tegangan motor pompa air. Paper ini mengusulkan inverter boost satu fasa untuk pompa air tenaga surya yang dapat menaikan sekaligus mengkonversikan tegangan dc menjadi tegangan ac tanpa menggunakan transformator. Modulasi inverter dirancang menggunakan metode Sinusoidal Pulse Width Modulation (SPWM) yang diimplementasikan dengan arduino uno. Pompa air tenaga surya diimplementasikan untuk penyediaan air bersih di Mesjid dengan menggunakan panel surya 300 WP. Hasil pengujian di lapangan menunjukan bahwa pompa air tenaga surya yang diusulkan telah bekerja dengan baik sesuai dengan yang diharapkan. Inverter boost satu fasa yang diusulkan telah dapat mengkonversikan tegangan panel surya sesuai dengan rating tegangan motor pompa air.
