利用晶闸管构成的交-直-交电压型变频电路的分析

Analysis of Circuit Structure of AC-DC-AC Frequency Converter by Using Thyristors

从总体方面概括地分析了交直交电压型变频电路的结构和各部分的作用。重点分析了逆变器部分的2种工作状态:稳定工作状态和换相过程。在分析稳定工作状态时,给出在6种不同的工作状态下负载相电压和负载线电压的大小,并在分析换相过程时,详尽地说明了6个换相过程中的2种。对电气系的本/专科学生的学习有一定帮助。

This thesis analyzes circuit structure of ACDCAC frequency converter in voltage type and function of each part briefly. It emphatically analyzes two kinds of working statestable working state and changing of the working course. While analyzing the stable working state, the article illustrates the phase voltage of load and the line voltage of load under six pieces of different working state in details.While analyzing changing of the working course, it illustrates two kinds among six changing course concretely and exhaustively. In this way, the reader can easily understand the other working course. In a word, the characteristic of this text is proceeding from readers′ angle to analyze classical problem, and it is suitable for students who are in electricity department.
