摘要

电力电子学,又称功率电子学(Power Electronics)。它主要研究各种电力电子器件，以及由这些电力电子器件所构成的各式各样的电路或装置，以完成对电能的变换和控制。它既是电子学在强电(高电压、大电流)或电工领域的一个分支，又是电工学在弱电(低电压、小电流)或电子领域的一个分支，或者说是强弱电相结合的新科学。电力电子学是横跨“电子”、“电力”和“控制”三个领域的一个新兴工程技术学科。

随着科学技术的日益发展,人们对电路的要求也越来越高,由于在生产实际中需要大小可调的直流电源,而相控整流电路结构简单、控制方便、性能稳定,利用它可以方便地得到大中、小各种容量的直流电能,是目前获得直流电能的主要方法,得到了广泛应用。

由于电力电子技术是将电子技术和控制技术引入传统的电力技术领域，利用半导体电力开关器件组成各种电力变换电路实现电能和变换和控制，而构成的一门完整的学科。故其学习方法与电子技术和控制技术有很多相似之处，因此要学好这门课就必须做好课程设计，因而我们进行了此次课程设计。因为整流电路非常重要，所以我此次课程设计做的是单相半波整流电路。

关键字电子学；整流器；开关器件

ABSTRACT

Power electronics, and power electronics (Power Electronics). It is mainly on the various power electronic devices, and is composed , and is composed of the power electronic devices of every kind of circuit or device, to complete the transfer and control of electric power. It is not only in power electronics (high voltage, high current) to a branch or electrical engineering, and electrical engineering in a weak (low voltage, low current) to a branch or electronic field, or is a new scientific power combining. Power electronics is across the "electronic", "power" and "control" three areas of an emerging engineering discipline.

With the development of science and technology, people on the circuit is also more and more high, due to the need of DC power supply with adjustable size in the actual production, and phase controlled rectifier circuit is simple in structure, convenient control, stable performance, it can be easily obtained in large and medium-sized, small capacity of various DC power, is currently the main method of DC electric energy, has been widely applied.

Because the power electronic technology is the technology of power electronic technology and control technology into the traditional, composed of a variety of power conversion circuits to achieve energy and transform and control using semiconductor power switch device, consisting of an integrated discipline. The learning method and electronic technology and control technology has many similarities, so to learn this course we must do a good job in curriculum design, we carried out the curriculum design. Because the rectifier circuit is very important, so I designed a single-phase half-wave rectifier circuit this curriculum.

Keywords electronics; rectifier; switching device
