摘要 随着汽车的普及以及储能技术的发展,车载电源的优化也越来越受关注。此设计通过采用DC/DC变换器和DC/AC逆变器两级结构,移相控制方式逆变器,以及对DSP2812芯片采用软件编程,使产生SPWM移相控制信号作为电路驱动,结合适当的保护电路,将较市场常见车载逆变电路效率提升25%左右。通过MULTISIM,MATLAB仿真和实物测试,实现了提供车载220 V电压的功能。 With the popularization of cars and development of energy storage technology ,the optimization of the battery loaded in the car is becoming more and more a concern. The design adopting the structure of dc/dc converter,dc/ac inverter and inverter with phase shift control combined with taking software programming in the chip of DSP2812 can produce the SPWM phase shift control signals which can be used as driving circuit.The efficiency,if unified with a appropriate protection circuit, will be enhanced by twenty-five percent compared with traditional market inverter circuit.The design achieve to function of supplying voltage with valid values for 220 V through the real test and simulation of MUTISIM ,MATLAB.
