“…In [275], a multi-winding transformer is used with each winding linked to full bridge cells. Besides, featuring a 200-1000V charging voltage range, three contactors or bidirectional switches are used, and then the output bridges can also be operated with two modes, which are parallel and series modes.…”

The powertrain voltages in battery electric vehicles (BEVs) have witnessed an upward trend due to advantages such as reduced runtime losses and extremely high DC fast charging power levels; aiding in reduced range anxiety and lower battery charging duration. This trend requires original equipment manufacturers (OEMs) to re-assess the design of electronic sub-assemblies (ESAs). Due to newly released DC fast charging standards, there are implications on the on-board charger (OBC), which is one of the ESAs in a BEV. This paper performs a comprehensive review of identifying system-level and use-case related challenges in transitioning on-board chargers to higher voltages compared to state-of-the-art, while considering the impact of newly introduced DC fast charging standards like Megawatt Charging Systems (MCS) and ChaoJi/ CHAdeMO 3.0. The existing research in academia and proof-of-concept designs compatible for high-voltage on-board charging sub-systems, such as the power factor correction (PFC) and isolated DC-DC conversion stages is consolidated. Due to the demand for integration driven by costoptimization targets, single-stage, traction-integrated, and auxiliary power unit (APU) integrated on-board chargers are discussed. Finally, the disparity between state-of-the-art technology and future requirements is defined to establish challenges and the direction of future research areas.

“…The use of DAB in 1 Mega-watt (MW) renewable offshore wind energy application has been investigated in [5], where the converter was configured to operate in buck mode using 12 kV input and 1.2 kV output voltages. Investigation of DAB converters for electric/hybrid vehicles has been carried out by [6][7][8][9][10]. In [6], the feasibility of air-cooled 7.5 KW Gallium nitride (GaN)-based DAB converters was designed and implemented for automotive battery charging.…”

“…The authors exploited 650 V GaN technology and the planar-based transformer operating at 200 kHz switching frequency. Even though, space optimization was not performed, the prototype achieved an efficiency of 98% for the voltage range of 400-500 V. Similarly, in [10], a wide output voltage range of 200-1000 V DAB converter for electric vehicle (EV) charging stations was proposed. In systems, such as uninterruptable power supplies (UPS), energy storage and transfer, a bidirectional DAB converter has been shown to be promising candidate [11].…”

“…The primary emphasis of recent research on dual active bridge (DAB) converters has been on enhancing efficiency through the development of modulation control strategies [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26], close loop control [27][28][29][30][31], converter circuit topology [26,27] and use of low loss switching devices [32,33]. The modulation control scheme for DAB converters has emerged as a significant research area, with a focus on optimizing existing modulation methods.…”

The main objective of this paper is to provide a thorough analysis of currently used modulation control schemes for single-phase bidirectional dual active bridge DC/DC converters. In this article, it will be shown that single phase shift, extended phase shift and dual phase shift modulation schemes are special cases of the triple phase shift (TPS) modulation scheme. The article aims to highlight six TPS switching modes and their complements with operational constraints. Unlike previous studies that regarded TPS as a complex scheme, this paper simplifies the analysis of each mode and aims to standardize the understanding of TPS modulation for dual active bridge (DAB) converters. Power equations, range of power transferred and zero-voltage switching (ZVS) are derived for all the modes under TPS without assuming fundamental component analysis. Additionally, a generic optimization algorithm is developed to show the advantages of TPS modulation, and thus, the analysis in this paper offers a valuable insight for single-phase DAB converter designers in identifying a wide range of optimization algorithms to achieve higher efficiency under TPS modulation. This analysis contributes to the advancement of bidirectional DAB converter technology and facilitates its application in various power electronic systems.
