摘　　要：为保护车载逆变器内部元器件和接入的用电设备不会在恶劣情况下发生损坏,设计了一款基于双极性TVS管保护的车载逆变器,主要包括推挽正激电路和全桥逆变电路。推挽正激电路将12V直流电压升压,全桥逆变电路再将电压逆变为220V/50Hz交流电压。介绍了车载逆变器的工作原理,研究了TVS管的工作原理和特性,提出了TVS管对电路的保护方案。最后,用saber仿真软件进行仿真,搭载了实物模型进行测试,对车载逆变电源实施了有效的保护。In order to protect the internal components and the inverter output load can not be damaged in the worst case, a design based on TVS car inverter tube protection, including push-pull forward circuit and full bridge inverter circuit. The push-pull forward circuit increases the 12V DC voltage to about 360V, and the full bridge inverter circuit converts the 360V voltage to 220V/50HZ AC voltage. This paper introduces the working principle of the vehicle mounted inverter, studies the working characteristics of the TVS tube, and puts forward the protection scheme of the TVS tube to the circuit. Finally, the saber simulation software is used to carry out the simulation, which is equipped with the physical test.
