基于DSP的电动汽车充电电源的设计
摘要
在当今社会,工业化速度加快,城市间的交流和沟通也变得越来越紧密,而推动这些快速发展的正是快速便利的交通。传统的交通工具都是以燃烧不可再生资源石油来提供动力的,而且未能完全燃烧的燃油将主要以二氧化碳和二氧化硫的形式排放到空气中,所以燃油汽车给人类带来了严重消耗能源和污染环境,因此,根据目前的发展状况,这种发展趋势很显然是不符合人类持久生存的规律的,因此各个国家相继向绿色清洁能源发展,为了保护人类的生存环境,近年来一些发达国家研究出了电动汽车,电动汽车主要是利用蓄电池中储存的电能作为动力源,减少有毒气体排放到空气中,同时节约了石油能源,因此对蓄电池进行充电就很重要了。本论文基于DSP拟设计一个电动汽车充电电源系统,对蓄电池充电,主要针对目前的发展现状,设计出清洁环保的汽车充电电源。
针对以上问题,本设计在研究基于DSP拟设计一个电动汽车充电电源系统,通过DSP的事件管理器产生PWM控制信号驱动可控硅,然后通过电力电子技术,AC-DC变换得到直流电源,最后给蓄电池供电,完成设计。因此本文主要从以下几个方面展开:
(1)DSP在本次设计的应用。本次设计运用DSP主要是为了给后面的电力电子电路提供可控硅的驱动信号,我们知道2000系列的DSP可提供带死区的PWM控制信号,在德州仪器,几乎已经将2000系列的DSP归结为MCU系列。
(2)电力电子技术在本次设计的应用。本次设计要完成给蓄电池充电,要获取一定的直流电源,因此,这里用到了电力电子技术,将交流电转化为直流电,最终给蓄电池供电,整套设计包涵了AC-DC电路,可控硅的触发电路,输出电压稳定电路。

Abstract
In today's society, speed of industrialization, exchange munication between cities has e more and more close, and promote the rapid development is rapid convenient means of transportation are non-renewable resources oil burning to provide power, and failure bustion of fuel will be mainly in the form of carbon dioxide and sulfur dioxide emissions into the air, so fuel cars brought serious energy and environmental pollution to human, therefore, according to the current development situation, the developing trend is clearly ply with the principle of enduring human survival, so one after another to the green clean energy development, various countries in order to protect the human survival environment, in recent years, some developed countries developed electric cars, electric cars, mainly using electrical energy stored in the storage battery as a power source, reduce poisonous gases into the air, at the same time, save oil energy, so it is very important for battery this paper, based on DSP is proposed to design a electric vehicle charging power supply system, the battery charging, according to the present situation of the development, design a clean environmental protection car battery pow
