Description

纯电动汽车交流大功率供电系统
技术领域
本发明涉及纯电动汽车供电系统，尤其是涉及纯电动汽车交流大功率供电系统。
背景技术
传统的纯电动汽车用逆变电源采用工业级逆变电源设计，其功率模块采用了工业级器件设计，这就大大降低了车载逆变器的稳定性和可靠性；而且传统的车载逆变电源采用DC-DC升压电路，系统输入与输出电气上没有隔离，存在较大的安全隐患。同时，传统的车载逆变电源功率设计比较小，而且散热方式采用风机风冷方式，持续工作时间较短，且系统IP等级（电气设备外壳对异物侵入的防护等级）比较低，已不能满足电动汽车逆变系统高功率、高稳定和高可靠性的需求。
发明内容
本发明目的在于提供一种纯电动汽车交流大功率供电系统。
为实现上述目的，本发明采取下述技术方案：
本发明所述的纯电动汽车交流大功率供电系统，包括水冷式逆变控制器、水冷式互耦型逆变变压器、逆变滤波器；所述水冷式逆变控制器CAN总线接口与整车控制器CAN总线接口相连接，水冷式逆变控制器高压输入接口通过车载高压配电盒预充电系统与车载电池单元相连接，水冷式逆变控制器高压输出接口与水冷式互耦型逆变变压器输入接口相连接，所述水冷式互耦型逆变变压器的内置温度传感器接口与水冷式逆变控制器信号输入接口相连接，水冷式互耦型逆变变压器输出接口与逆变滤波器输入接口相连接，所述逆变滤波器输出接口由单相220V交流电插座和三相380V交流电插座组成。
本发明优点在于逆变系统设计采用分离部件设计和独立于整车驱动系统输出设计，系统设计灵活，设计充分考虑电磁兼容性，结构简单紧凑，易于装配，各部件设计易于产品化，并具有高安全、高稳定和高可靠性。

具体实施方式
下面结合附图对本发明的实施例作详细说明，本实施例在以本发明技术方案为前提下进行实施，给出了详细的实施方式和具体的操作过程，但本发明的保护范围不限于下述实施例。
如图1-5所示，本发明所述的纯电动汽车交流大功率供电系统，包括水冷式逆变控制器1、水冷式互耦型逆变变压器2、逆变滤波器3；水冷式逆变控制器1的CAN总线接口4与整车控制器CAN总线接口相连接，水冷式逆变控制器1的高压输入接口5通过车载高压配电盒预充电系统与车载电池单元相连接，水冷式逆变控制器1的高压输出接口6与水冷式互耦型逆变变压器2输入接口7相连接，水冷式互耦型逆变变压器2的内置温度传感器接口8与水冷式逆变控制器信号输入接口相连接，水冷式互耦型逆变变压器2输出接口9与逆变滤波器3输入接口10相连接，逆变滤波器3输出接口由单相220V交流电插座11和三相380V交流电插座12组成。
本发明采用分离的水冷式逆变控制器1、水冷式互耦型逆变变压器2、逆变滤波器3组成；水冷式逆变控制器采用SEVCON公司的水冷式逆变控制器，设计有CAN总线接口4，实现逆变系统的整车控制以及直流到交流的转换和逆变输出电压的控制和过流、过压、过温控制及保护。由于水冷式逆变控制器1设计有高压输入接口5和高压输出接口6，独立于整车电机驱动系统，因此不影响整车驱动系统。水冷式逆变控制器1的信号接口实现对水冷式互耦型逆变变压器2的温度检测和控制，水冷式逆变控制器1的控制电源采用低压12V，易于实现逆变系统的控制。
水冷式互耦型逆变变压器2实现了逆变系统输入和系统输出的电气隔离，具有单相220V交流电插座11和三相380V交流电插座12输出独立设计，保证两种电源系统独立输出。水冷式互耦型逆变变压器2采用内置PT1000温度传感器设计，由水冷式逆变控制器1采集和进行逆变系统输出控制及保护，保证系统输出安全可靠。水冷式互耦型逆变变压器2防护等级按IP67设计，易于实现逆变系统的整车布置。
逆变滤波器3采用TDK三相薄膜电容和三相滤波器，使逆变系统输出电压为纯净的正弦波，保证逆变系统输出带载和入网的安全和稳定性，逆变滤波器3和逆变系统输出采用集成设计，避免逆变系统输出引入干扰，保证系统输出可靠性。
本发明电气工作原理简述如下：
车载仪表盘充放电开关切换到放电状态，整车控制器由休眠状态切换到唤醒状态，整车控制器控制水冷式逆变控制器1低压上电，水冷式逆变控制器1完成低压上电后整车控制器控制车载高压配电盒预充电系统充电，预充电完成之后车载电池单元直流高压通过车载高压配电盒输入给水冷式逆变控制器1，水冷式逆变控制器1将输入的直流高压逆变成交流电压；水冷式逆变控制器1输出的交流电压经过水冷式互耦型逆变变压器2进行升压和电气隔离，水冷式互耦型逆变变压器2输出升压和隔离后的交流电压经过逆变滤波器3进行交流电压滤波输出纯净的交流电压，逆变滤波器3输出的纯净交流电压通过集成在逆变滤波器3上的大功率单相220V交流电插座11和三相380V交流电插座12输出。
