摘　　要：介绍了车载逆变电源的工作原理,重点阐述了主电路参数设置和控制电路的控制策略。以Freescale单片机MC9S12DG128为控制核心研制了样机,做了相关实验研究,给出部分波形和实验数据,验证了系统设计的正确性和合理性。实验结果表明,可实现由12 V直流电转换为工频交流电(220 V,50 Hz)的电源装置,电压波形呈正弦且失真小,装置转化效率较高。The paper introduced the working principle of the vehicle inverter, and emphatically expounded the main circuit parameters setting and the control strategy of control circuit. A prototype was developed based on the MC9S12DG128 MCU of Freescale series, and the experimental study was completed, the correctness and rationality of the system design are verified by the waveform and the experimental data. The experimental results indicated that the power supply device can be realized by the 12V DC power conversion to power frequency alternating current （220V, 50Hz）, the voltage waveform was sinusoidal and the distortion was small, and the conversion efficiency of the device was higher.
