【摘要】：为了解决当前电动汽车充电模块效率低、功率小的缺点,提出了一种基于混合控制式交错并联LLC谐振技术的非车载式电动汽车充电模块整体设计方案。所述方案输入侧为VIENNA电路,输出侧为交错并联LLC谐振DC/DC变换器。采用交错并联技术减小输出电流纹波,提高充电模块输出功率的同时,采用移相变频混合控制策略,使得谐振变换器工作在较窄的频率范围之内,因此降低了磁性元器件设计难度,提高了充电模块的转换效率以及功率密度。给出了充电模块整体电路拓扑设计、各模块工作原理以及控制策略,研制了20kW原理样机,与纯变频式交错并联LLC谐振变换器充电模块的对比分析验证了所述方法的可行性。
[Abstract]:In order to solve the problems of low efficiency and low power of current charging module of electric vehicle, a new design scheme of charging module for non-vehicle-borne electric vehicle based on hybrid controlled staggered parallel LLC resonance technology is proposed. The input side of the scheme is a VIENNA circuit and the output side is a staggered parallel LLC resonant DC / DC converter. Using staggered parallel technology to reduce the output current ripple, improve the output power of charging module, and adopt the phase-shift frequency conversion hybrid control strategy to make the resonant converter work in a narrow frequency range. Therefore, the design difficulty of magnetic components is reduced, and the conversion efficiency and power density of charging module are improved. The whole circuit topology design, working principle and control strategy of the charging module are given. A 20kW prototype is developed. The feasibility of the proposed method is verified by comparing with the charging module of the pure variable frequency interleaving parallel LLC resonant converter.
