电动汽车充电技术已经取得了长足的进步，并在电动汽车的广泛采用方面取得了进展。然而，为了进一步加速电动汽车的发展，电动汽车的充电时间需要大幅改善。为了应对这一挑战，开发一种能够实现更快、更高效和更有效的电动汽车充电方式的技术至关重要。为了应对这一挑战，开发一种能够实现更快、更高效和更有效的电动汽车充电方式的技术至关重要。目前的快速充电解决方案涉及笨重的中压低压变压器，这增加了电动汽车充电站的安装复杂性。因此，本文提出了一种利用中压 (MV) 双有源桥 (DAB) 转换器的替代供电解决方案。所提出的架构旨在直接连接中压电网，以实现高功率、快速充电能力，同时无需安装中压-低压变压器。 MV DAB 转换器利用 3.3 kV SiC MOSFET 来实现下一代 800 V EV 充电系统。本文还通过改变转换器的输入（直流链路）电压和开关频率，为中压 DAB 转换器提供了扩展的零电压开关 (ZVS) 方案。根据系统规格和要求，开发了缩小版的12 kW MV DAB样机，并通过实验模拟和验证了其充电操作以及扩展的ZVS方案。
Electric vehicle charging technology has come a long way and seen progressive outcomes toward a wide adoption of EVs. To further accelerate the EV evolution, though, the recharging time of electric vehicles will require much improvement. In order to address such a challenge, it is critical to develop a technology that would enable faster, more efficient, and more effective ways of charging an electric vehicle. In order to address such a challenge, it is critical to develop a technology that would enable faster, more efficient, and more effective ways of charging an electric vehicle. The current fast-charging solution involves a heavy and bulky MV-LV transformer, which adds installation complexity for EV charging stations. Therefore, this paper presents an alternative power-delivery solution utilizing a medium-voltage (MV) dual-active-bridge (DAB) converter. The proposed architecture is designed to directly interface the MV grid for high-power, fast-charging capability while eliminating the need for the installation of the MV-LV transformer. The MV DAB converter utilizes 3.3 kV SiC MOSFETs to realize the next 800 V EV charging system. This paper also provides an extended zero-voltage-switching (ZVS) scheme for the MV DAB converter by varying the input (DC-Link) voltage and the switching frequency of the converter. With the system specifications and requirements, a scaled-down 12 kW MV DAB prototype was developed, and its charging operation along with the extended ZVS scheme was simulated and verified by experiments.
