Description

7kW双向电动汽车非车载直流充电模块
技术领域
本发明涉及双向充放电技术领域，具体为7kW双向电动汽车非车载直流充电模块。
背景技术
电动汽车取代传统能源汽车已成为必然趋势。充电基础设施需要更长时间的规划才能基建完善。同时，充电桩后期运营工作同样正在阻碍充电桩的发展，与高速发展的电动汽车行业相比，充电桩设施分布不均，充电桩比例失衡等问题使得目前充电桩明显处于供不应求的状态，这在一定程度上影响了电动汽车的普及。
V2G(vehicle-to-grid)技术可实现电网与电动汽车(EV:electric vehicle)之间能量的双向流动，EV用户可以是能量消耗者，也可以是能量供应者。在合理控制下，V2G技术的应用可提供调峰、调频以及电压控制，增加对间歇性的可再生能源的消纳，维持电力系统安全稳定运行。而V2G技术的关键技术之一就是高性能双向充放电技术。
目前来看用户对电动汽车最为关心的问题就是续航和充电，如今电动汽车所使用的的电池容量越来越大，续航问题基本得到解决。而快速充电就成为了亟待解决的问题，提高充电电压就是一种解决途径。现有技术还存在双向充放电高效率不佳、稳定性不高的技术问题，基于此，本发明设计了7kW双向电动汽车非车载直流充电模块，以解决上述问题。
发明内容
本发明的目的在于提供双向电动汽车非车载直流充电模块，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：7kW 500V双向电动汽车非车载直流充电模块，包括输入EMC电路、缓启动电路、单相两交错图腾柱PFC电路、双向CLLC电路、输出滤波电路、输入电流电压采样电路、隔离驱动电路、输出电流电压取样电流、辅助电源电路和DSP控制电路；
当单相交流电通过正向输入EMC电路，输入电流电压采样电路采集输入电压信号传输给DSP控制电路判断输入交流电无异常，从而控制缓启动电路中的继电器吸合，再输入到单相两交错图腾柱PFC电路，整流升压至双向CLLC电路所需的直流电压，双向CLLC电路中的初级四个MOS做全桥LLC谐振并通过隔离变压器相次级做电压变换及功率传递，次级四个MOS做同步整流控制，将交流方波信号整流直流电，通过输出滤波电路滤波后输出平滑的直流电；
缓启动电路中继电器K1开关的负载端并上PTC电阻，PFC的工作模式为BOOST模式，通过SPWM调制技术实现对输入电流的调整；
当200-500V直流电反向输入到输出滤波电路，同时DSP控制电路接收到反向输出命令时，双向CLLC电路中的次级四个MOS做全桥LLC谐振并通过隔离变压器相初级做电压变换及功率传递，初级四个MOS做同步整流控制，将交流方波信号整流直流电，通过单相两交错图腾柱PFC电路转换成交流正弦波信号经过启动电路中的继电器输入到输入EMC电路滤波，对外输出单相正弦波交流电；
在上述方向输出过程中，DSP控制电路需要实时通过输入电流电压采样电路和输出电流电压采样电路检测电流电压信号，来控制反向输出的状态；
辅助电源电路给整个充电模块中的电子元器件提供稳定的各种电压的电源；
充电模块将CLLC输出的直流方波通过电容滤平滑后，再通过共模电感L1、电容C5、C6、C7及Y电容Cy1、Cy2、Cy3、Cy4组成的输出EMC电路消除共模干扰，增强充电模块的抗干扰性，反向输入时它作为输入EMC电路也起到降低输入干扰的功能。
优选的，所述输入EMC电路采用由X电容C1、C2、C3，共模电感L1、L2和Y电容CY1、CY2、CY3、CY4组成的两级Π型滤波，由压敏电阻VR1、VR3以及气体放电管GDT1组成了防雷击电路。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
本发明提供一种技术方案：7kW 500V双向电动汽车非车载直流充电模块包含以下电路，如图1所示：输入EMC电路，缓启动电路，单相两交错图腾柱PFC电路，双向CLLC电路，输出滤波电路，输入电流电压采样电路，隔离驱动电路，输出电流电压取样电路，辅助电源电路和DSP控制电路。
当单相交流电通过正向输入EMC电路，输入电流电压采样电路采集输入电压信号传输给DSP控制电路判断输入交流电无异常，从而控制缓启动电路中的继电器吸合，再输入到单相两交错图腾柱PFC电路，整流升压至双向CLLC电路所需的直流电压，双向CLLC电路中的初级四个MOS做全桥LLC谐振并通过隔离变压器相次级做电压变换及功率传递，次级四个MOS做同步整流控制，将交流方波信号整流直流电，通过输出滤波电路滤波后输出平滑的直流电。
当200-500V直流电反向输入到输出滤波电路，同时DSP控制电路接收到反向输出命令时，双向CLLC电路中的次级四个MOS做全桥LLC谐振并通过隔离变压器相初级做电压变换及功率传递，初级四个MOS做同步整流控制，将交流方波信号整流直流电，通过单相两交错图腾柱PFC电路转换成交流正弦波信号经过启动电路中的继电器输入到输入EMC电路滤波，对外输出单相正弦波交流电。在上述方向输出过程中，DSP控制电路需要实时通过输入电流电压采样电路和输出电流电压采样电路检测电流电压信号，来控制反向输出的状态。
辅助电源电路给整个充电模块中的电子元器件提供稳定的各种电压的电源。
如图2所示为输入EMC电路，电路采用由X电容C1、C2、C3，共模电感L1、L2和Y电容CY1、CY2、CY3、CY4组成的两级Π型滤波，可有效降低充电模块的EMC干扰。由压敏电阻VR1、VR3以及气体放电管GDT1组成了防雷击电路。
图3为缓启动电路+单相两交错图腾柱PFC电路原理图，缓启动电路中继电器K1开关的负载端并上PTC电阻。由于PTC呈正温度特性，即当温度上升时，其自身的阻值会逐渐增大。在交流电刚刚插入时，继电器K2闭合，K1处于断开状态，此时母线上的电容电压为0，电流通过PTC电阻给电容预充电，使整个系统缓启动，当电容充满即缓启动完成后，继电器闭合使PTC短路，电路进入正常工作状态。如果负载端异常，即在继电器尚未闭合时候就工作，此时PTC电阻上就会有大电流走过，PTC功耗使自身温度升高，其自身的阻抗也随之升高，从而起到关断电路的作用。
当Vsen_L与Vsen_N两点电压Uab为正时：开通Q4、Q6，此时Uab给电感L1储能；然后关闭Q4、Q6，电感L1中的存储能量向负载释放。由于Q1的反向钳位作用，因此负载的电压不能向Uab反灌从而实现升压作用。L1、Q1、Q4与L2、Q2、Q5交错工作。PFC的工作模式为BOOST模式，通过SPWM调制技术实现对输入电流的调整。
如图4所示，500V的高压输出时，充电模块采用的是全桥LLC拓扑，在变压器初次级两端为对称结构，当左边作为输入端时，通过原边四个开关mos管Q1、Q2、Q3、Q4切换的频率控制整个原边LLC回路的频率控制整个原边LLC回路的频率，副边四个MOS管为同步整流模式。反之，当左边作为输入端时，通过副边四个开关mos管Q5、Q6、Q7、Q8切换的频率控制整个副边LLC回路的频率控制整个副边LLC回路的频率，原边四个MOS管为同步整流模式。双向CLLC电路根据不同的输出状态，采用了PFM控制，移相控制，BOOST升压控制等综合的控制策略方案，以达到最佳的系统输出状态。
如图6所示，充电模块将CLLC输出的直流方波通过电容滤平滑后，再通过共模电感L1、电容C5、C6、C7及Y电容Cy1、Cy2、Cy3、Cy4组成的输出EMC电路消除共模干扰，增强充电模块的抗干扰性。反向输入时它作为输入EMC电路也起到降低输入干扰的功能。
本发明中作为另一个技术方案，7kW 1000V双向电动汽车非车载直流充电模块包含以下电路，如图1所示：输入EMC电路，缓启动电路，单相两交错图腾柱PFC电路，双向CLLC电路，输出滤波电路，输入电流电压采样电路，隔离驱动电路，输出电流电压取样电流，辅助电源电路和DSP控制电路。
仅区别于7kW 500V双向电动汽车非车载直流充电模块的实施方式，缓启动电路中继电器K1开关的负载端并上PTC电阻，通过SPWM调制技术实现对输入电流的调整；
仅区别于7kW 500V双向电动汽车非车载直流充电模块的实施方式，图5中，采用两组3.3kW CLLC输出，图7中，充电模块将CLLC输出两路通过3个继电器K1、K2、K3控制它们的输出，当输出电压<500V，继电器K1、K2闭合，K3断开，两路并联输出；当输出电压>500V，继电器K3闭合，K1、K2断开，两路串联输出，然后通过共模电感L1、电容C5、C6、C7及Y电容Cy1、Cy2、Cy3、Cy4组成的输出EMC电路消除共模干扰，增强充电模块的抗干扰性，反向输入时它作为输入EMC电路也起到降低输入干扰的功能。
