Two pulse bridge converter: A two pulse bridge converter is achieved as shown in Fig. 3.22 from two midpoint converters. They are connected in series on the dc side and…
Two pulse mid point converter: Two pulse mid point converter are, in general, single phase converters. The pulse number of the converter indicates the frequency of the ripple voltage superimposing…
Phase Controlled Line Commutated Converters: In these Phase Controlled Line Commutated Converters, the commutation voltage, i.e. the voltage required to transfer current from one thyristor to the other, is provided…
Electric Converter: Electric Converter - The speed of a dc motor can be varied by varying the armature voltage or the field current, for which a variable dc supply is…
DC Motor Speed Control: In the foregoing sections we discussed the torque-speed characteristics of dc motors, bringing out the effects of armature voltage variation and field current on them. The…
DCS System: A DCS System is preferred over a central computer system for the following reasons. Central Computer System (CCS) exposes the plant to the risk that the system might fail.…
Self Oscillating Converter (Transistorized Chopper Circuit): Self Oscillating Converter (Transistorized Chopper Circuit) - A Transistorized dc to ac converter suitable for low level dc signal is illustrated in Fig. 14.30.…
