随着电动汽车市场大规模增长，电动汽车充电设备的应用也随之增多。针对传统电动汽车充电变换器电压增益范围小、低电压输出时效率低且二次侧整流二极管电压应力高的缺点，改进了1种飞跨电容式三电平LLC谐振变换器拓扑，并提出1种变脉宽Burst控制策略，提高了低电压输出时的效率。通过由变频控制、变脉宽Burst控制策略组成的混合控制，实现宽电压输出并用基波近似法分析变脉宽Burst控制策略的增益范围。最后搭建1台最高功率为2 000 W的样机，验证了所改进的飞跨电容式三电平LLC谐振变换器新拓扑、变脉宽Burst控制策略的可行性。

With the massive growth of the electric vehicle (EV) market, the applications of EV charging equipment have also increased. Aimed at the disadvantages of traditional EV charging converters such as a small voltage-gain range, a low efficiency in low voltage output mode and a high voltage stress in rectifier diodes on the secondary side, the topology of a three-level LLC resonant converter with integrated flying-capacitor cell is improved, and a Burst control strategy with variable pulse width is proposed to enhance the efficiency in low voltage output mode. Through the hybrid control composed of pulse frequency modulation and the proposed Burst control strategy with variable pulse width, a wide output voltage is achieved, and the voltage-gain range under the Burst control strategy with variable pulse width is analyzed using first harmonic approximation. Finally, an experimental prototype with maximum power of 2 000 W was built, and results verified the feasibility of the novel topology of the improved three-level LLC resonant converter with integrated flying-capacitor cell and its Burst control strategy with variable pulse width.
