基于matlab的电力电子技术仿真实验设计
摘 要
20世纪60年代发展起来的电力电子技术，使电能可以交换和控制，产生了现代各种高效节能的新型电源和交直流调速装置，为工业生产，交通运输，楼宇办公家庭自动化提供了现代化的高新技术，提高了生产效率和人们的生活质量，使人类社会生产生活发生了巨大变化。
电力电子技术由于电力电子器件自身的非关联性，给电力电子电路和系统的分析了一定的复杂性和困难，一般常用波形分析和分段线性化处理的方法来研究电力电子电路。现代计算机仿真技术为电力电子电路和系统的分析提供了崭新的方法，可以使复杂的电力电子电路系统的分析和设计变得更加容易和有效。
MATLAB软件是由美国Math Works公司推出的用于数值计算和图形处理的科学计算软件系统被誉为“巨人肩上的工具”MATLAB早期主要用于控制系统的仿真，经过不断扩展已经成为包含通信电气工程优化控制等诸多领域的科学计算软件，可以用于电力电子电路和电力拖动控制系统的仿真。
因此本课题在MATLAB的基础上进行电力电子变流电路的仿真，运用现代仿真技术研究和比较各种电力电子变流电路。

Abstract
In the 1960s developed the power electronics. enabled the electrical energy to be possible to exchange and to control, has produced the modern each kind of highly effective energy conservation new power source and the alternating and direct speeder, was the industrial production, the transportation, the building work household automation has provided the modernized high technology and new technology, raised the production efficiency and people's quality of life, caused the human society to produce the life to have the immense changes.
The power electronics as a result of power electronics device own non-relatedness, for the power electronics circuit and system's analysis certain complexity and the difficulty, generally the commonly used waveform analysis and the partition linearization processing method studied the power electronics circuit. The modern computer simulation technology has provided the brand-new method for the power electronics circuit and system's analysis, may cause the complex power electronics circuit system's analysis and the design becomes is easier and is effective.
The MATLAB is Corporation promotes by American Math Works uses in the numerical calculus and the graphic processing science computation software system is honored as “on the giant shoulder's tool” the MATLAB early time mainly to use in control system's simulation, passed through expands unceasingly already became contains the correspondence electrical engineering optimization control and so on many domains the science computation software, might use in the power electronics circuit and the electric drive control system's simulation.
This topic carries on the power electronics electron variable current electric circuit's simulation in the MATLAB foundation, studies and compares each kind of power electronics electron variable current electric circuit using the modern
