Line-Commutated Converters and Inverters

  • Chapter
An Introduction to Thyristors and Their Applications

Abstract

The method by which AC supply voltage is used for the commutation of conducting SCRs has been discussed in Chapter 6; it is very convenient for both rectification and inversion in phase-controlled bridge circuits and midpoint-connection circuits. This method of commutation is referred to as class F type of commutation (see Chapter 8), and is also known as line commutation. All types of AC to variable voltage DC converters used for motor control and regulated power supplies, in both of which the AC input current is made continuous by a large reactor on the DC side, make use of line commutation without any external commutating components. The input-output characteristics of such line-commutated converters will be considered in detail in this chapter. The effect of source impedance of various types (R, L, or C) on the output voltage, and the minimum value of inductance required on the DC side to provide continuous load current for both active and passive loads will also be discussed.
