电力电子技术：一门新兴的应用于电力领域的电子技术
电力电子技术相关论文选题方向怎么写
[电子机械论文] 电力电子技术论文现代电源技术是应用电力电子半导体器件，综合自动控制、计算机(微处理器)技术和电磁技术的多学科边缘交又技术。在各种高质量、高效、高可靠性的电源中起关键作用，是现代电力电子技术的具 体应用。 当前，电力电子作为节能、节才、自动化、智能化、机电一体化的基础，正朝着应用技术高频化、硬件结构模块化、产品性能绿色化的方向发展。在不远的将来，电力电子技术将使电源技术更加成熟、经 济、实用，实现高效率和高品质用电相结合。2 模块化 模块化有两方面的含义，其一是指功率器件的模块化，其二是指电源单元的模块化。我们常见的器件模块，含有一单元、两单元、六单元直至七单元，包括开关器件和与之反并联的续流二极管，实质上都属于“标准”功率模块(SPM)。近年，有些公司把开关器件的驱动保护电路也装到功率模块中去，构成了“智能化”功率模块(IPM)，不但缩小了整机的体积，更方便了整机的设计制造。实际上，由于频率的不断提高，致使引线寄生电感、寄生电容的影响愈加严重，对器件造成更大的电应力(表现为过电压、过电流毛刺)。为了提高系统的可靠性，有些制造商开发了“用户专用”功率模块(ASPM)，它把一台整机的几乎所有硬件都以芯片的形式安装到一个模块中，使元器件之间不再有传统的引线连接，这样的模块经过严格、合理的热、电、 机械方面的设计，达到优化完美的境地。它类似于微电子中的用户专用集成电路(ASIC)。只要把控制软件写入该模块中的微处理器芯片，再把整个模块固定在相应的散热器上，就构成一台新型的开关电源装置。由此可见，模块化的目的不仅在于使用方便，缩小整机体积，更重要的是取消传统连线，把寄生参数降到最小，从而把器件承受的电应力降至最低，提高系统的可靠性。另外，大功率的开关电源，由于器件容量的限制和增加冗余提高可靠性方面的考虑，一般采用多个独立的模块单元并联工作，采用均流技术，所有模块共同分担负载电流，一旦其中某个模块失效，其它模块再平均分担负载电流。这样，不但提高了功率容量， 在有限的器件容量的情况下满足了大电流输出的要求， 而且通过增加相对整个系统来说功率很小的冗余电源模块，极大的提高系统可靠性，即使万一出现单模块故障，也不会影响系统的正常工作，而且为修复提供充分的时间。 3 数字化 在传统功率电子技术中，控制部分是按模拟信号来设计和工作的。在六、七十年代，电力电子技术完全是建立在模拟电路基础上的。但是，现在数字式信号、数字电路显得越来越重要，数字信号处理技术日趋完善成熟，显示出越来越多的优点:便于计算机处理控制、避免模拟信号的畸变失真、减小杂散信号的干扰(提高抗干扰能力)、便于软件包调试和遥感遥测遥调，也便于自诊断、容错等技术的植入。所以，在八、九十年代，对于各类电路和系统的设计来说，模拟技术还是有用的，特别是:诸如印制版的布图、电磁兼容(EMC) 问题以及功率因数修正(PFC)等问题的解决，离不开模拟技术的知识，但是对于智能化的开关电源，需要用计算机控制时，数字化技术就离不开了。 4 绿色化 电源系统的绿色化有两层含义:首先是显著节电， 这意味着发电容量的节约，而发电是造成环境污染的重要原因，所以节电就可以减少对环境的污染;其次这些电源不能(或少)对电网产生污染，国际电工委员会(IEC)对此制定了一系列标准，如IEC555、IEC917、IECl000等。事实上，许多功率电子节电设备，往往会变成对电网的污染源:向电网注入严重的高次谐波电流，使总功率因数下降，使电网电压耦合许多毛刺尖峰，甚至出现缺角和畸变。20世纪末，各种有源滤波器和有源补偿器的方案诞生，有了多种修正功率因数的方法。这些为2l世纪批量生产各种绿色开关电源产品奠定了基础。 现代电力电子技术是开关电源技术发展的基础。随着新型电力电子器件和适于更高开关频率的电路拓扑的不断出现，现代电源技术将在实际需要的推动下快速发展。在传统的应用技术下，由于功率器件性能的限制而使开关电源的性能受到影响。为了极大发挥各种功率器件的特性，使器件性能对开关电源性能的影响减至最小，新型的电源电路拓扑和新型的控制技术，可使功率开关工作在零电压或零电流状态，从而可大大的提高工作频率，提高开关电源工作效率，设计出性能优良的开关电源。 总而言之，电力电子及开关电源技术因应用需求不断向前发展，新技术的出现又会使许多应用产品更新换代，还会开拓更多更新的应用领域。开关电源高频化、模块化、数字化、绿色化等的实现，将标志着这些技术的成熟，实现高效率用电和高品质用电相结合。这几年，随着通信行业的发展，以开关电源技术为核心的通信用开关电源，仅国内有20多亿人民币的市场需求，吸引了国内外一大批科技人员对其进行开发研究。开关电源代替线性电源和相控电源是大势所趋，因此，同样具有几十亿产值需求的电力操作电源系统的国内市场正在启动，并将很快发展起来。还有其它许多以开关电源技术为核心的专用电源、工业电源正在等待着人们去开发。
