Wesentliche Ergebnisse der Arbeit,ectification 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 a

,Schlußfolgerungen für den Gesetzgeber,e third type, known as the ., will be considered here. The bridge configuration is widely used for controlled rectification (Chapter 6) and also for line-commutated inverters (Chapter 7). The main features of such a configuration are: (a) for rectifiers, there is no residual flux in the input transf

Thyristors,The basic properties and applications of thyristors have been explained in Chapter 1. Since the SCR is the most widely-used member of the family of thyristors, a more detailed analysis of its operation and characteristics is given here. The other devices will be discussed in Chapter 4.

AC Power Control,ntrol. In AC circuits, the SCR can be turned on by the gate at any angle α with respect to the applied voltage. This angle α is the .. Power control is obtained by varying the firing angle, and this is known as ..
