“…The relationship between phase shift D 3 and other phase shifts is shown in (3), and the timing diagram is presented in Figure 2. Numerous studies have presented various approaches to phase-shift control, such as single-phase-shift (SPS) control, extend-phase-shift (EPS) control, dual-phase-shift (DPS) control, and notably, triple-phase-shift (TPS) control [21][22][23][24][25][26][27][28][29][30][31][32]. TPS offers various phase-shift control combinations through the control of D 1 , D 2 and D φ .…”

An optimal modulation scheme with triple-phase-shift (TPS) control could increase the efficiency in the entire load range for a dual-active-bridge (DAB) converter under wide output voltage range conditions. Therefore, this study proposes a convergent approach to TPS mode selection, coupled with an optimal modulation scheme, ensuring the circuit’s efficiency over the entire range in the realm of a high-power and high-efficiency battery charger for electric vehicles. The convergent approach to TPS mode selection also reduces the numerous cases for small-signal analysis through general average modeling. After verifying the small-signal models under various voltage transfer ratios and load conditions to verify the stability, a converter prototype with a rated power of 15 kW is built and tested. Thus, a peak efficiency of 97.7% can be achieved.

“…Different types of switching modulation techniques such as single-phase shift (SPS) with variable of phase shift angle, dual-phase shift (DPS) with variables of phase shift angle and duty ratio of one bridge, and triple-phase shift (TPS) with variables of phase shift angle and duty ratios of two bridges are utilized for DAB [131]. Although DAB uses fewer passive components compared to resonant converters, securing ZVS switching for a wide range of EV battery voltage especially at light to medium load is quite challenging with SPS modulation.…”

“…For the implementation of dynamic control of DAB converter, common practices among researchers include small signal modeling and discrete-time average method for multi-phase shift modulation that can capture the dynamics of the system [131], [210]. The dynamic control mechanisms are usually categorized mostly into three types such as power computation-based control, direct inductance current control, and load current feedforward technique [211].…”

Wide-scale adoption and projected growth of electric vehicles (EVs) necessitate research and development of power electronic converters to achieve high power, low-cost, and reliable charging solutions for the EV battery. This paper presents a comprehensive review of EV off-board chargers that consist of acdc and dc-dc power stages from the power network to the EV battery. Although EV chargers are categorized into two types, namely, on-board and off-board chargers, it is essential to utilize off-board chargers for dc fast and ultra-fast charging so that volume and weight of EV can be reduced significantly. Here, we discuss the state-of-the-art topologies and control methods of both ac-dc and dc-dc power stages for off-board chargers, focusing on technical details, ongoing progress, and challenges. In addition, most of the recent multiport EV chargers integrating PV, energy storage, EV, and grid are presented. Moreover, comparative analysis has been carried out for the topologies and the control schemes of ac-dc rectifiers, dc-dc converters, and multiport converters in terms of architecture, power and voltage levels, efficiency, bidirectionality, control variables, advantages, and disadvantages which can be used as a guideline for future research directions in EV charging solutions.INDEX TERMS Charging stations, converter control, converter topologies, DC fast chargers, electric vehicle (EV), EV fast chargers, multilevel AC-DC converter, multiport converter, off-board charger.
