摘　　要：提出基于单片机和TL494芯片的车载逆变电源的系统设计。TL494作为前级推挽直流升压电路的控制器,完成了将12v直流电转换为320V直流电的控制;单片机完成了对后级全桥逆变及保护电路的控制;在MATLAB环境下对设计电路进行了建模仿真,仿真结果表明,该逆变电源系统具有良好的动态性能和稳态精度。This paper shows a system design of car inverter based on single chip microcomputer and TL494 chip.TL494 as the controller of push-pull dc booster circuit,completes the converter from dc 12 v to 320 v; ATmega16 completes the control of full bridge inverter and protection circuit.The system model is built with MATLAB and the simulation experiment results show that this system has good dynamic performance and steady precision.
