because thyrister doesn't allow the current to flow unless there is a current flow into the gate. this current must be dc, and the rating of this current depends on the type of thyrister.
A bridge rectifier rectifies AC to DC. But it can not regulate the DC level. The higher the AC input ..the higher the DC output. No Control. A Thyrister is a member of the four layer device familt called Sillicon CONTROLED Rectifiers. Controller Rectifier. Thyristors have a gate lead .They can not conduct in the reverse direction. Tey may conduct in the forward biased direction if they are gated on. By choosing how early in the forward biased half cycle you gate a thyrister on you CONTROL the level of currnt or voltage out of the bridge .
No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .
You need a DC power supply in order to connect a 24v DC motor to household power.
because it provides direct current in home some equipment need alternating current so we can not use dc supply in home
no... run tv with dc supply
Yes but only up to a load torque of 8/9 of the rated torque.
You need alternating current for a transformer, for DC you would have to interrupt the power supply to make it effectively DC pulses.
The transformer cannot be used in the DC supply because it keeps on alternating its current, whereas the DC supply current should be constant.
No, you need DC.
You would need a 12VDC to 120VAC power supply.
dc supply is used for control circuit because dc current is an independent source .
Variable dc supply is applicable in loads that are variable.
