SATURABLE-CORE REACTOR
SATURABLE-CORE REACTOR193. Saturable-core reactor. In many control circuits it is desirable to be able to control the value of the inductive reactance. This can often be accomplished advantageously by means of a device called a saturable-core reactor. A saturable-core reactor consists of a magnetic core associated with dc and ac windings. A common form of construction is shown in Fig. 5.88. When there is no current in the dc winding, the inductive reactance of the ac winding will be high, since there will be a high rate of change of flux with current. If sufficient direct current is passed through the dc winding to saturate the magnetic core, then the chang…
