What happens if dc supply is given to transformer

So in the given case ie, for DC input,no emf produced in primary . This voltage do not affect the secondary winding . This will happen only in AC supply. With DC there is no induced EMFs and the current is controlled only by t. There would be no current on the other side of the transformer , unless the power of the source was constantly modulated.

Does transformer work on DC Supply ?

What you are describing is essential to all power electronics today.

The basic principle are the Buck (pulse, step down) and Boost (pulse, step up) typologies. I assume you know that all electrical and electronic components work on smoke, which is injected at the factory. We know this is true, because if anything happens that allo. The dc supply is given to transformers are may get damege what is region?

Why current lags voltage in an inductive circuit. When Dc supply is given to primary of transformer it draws heavy current from the DC source due to absence of back emf and burnt out. Because the dc current not varying with time it has constant value throught the period. Transformer Name Plate Details Explained . If dc power is supplied to transformer following things will happen 1. If winding resistance is high compare to applied voltage then only contant flux . So if some one ask this question in interview or somewhere. AC and DC relays are constructed differently.

Long answer: A motor will only rotate if it experiences unidirectional torque. For production of emf the flux must be alternating in nature (lenz law). A transformer is made from inductors (connected by metal cores ). Hi sanyogeeta, You can give input for transformer from both sides, transformer is designed for the same.

If the battery supplying dc is connected in the wasy such that the diode is forward biased ,then only the drop of 0. V(Si) will appear on it and rest will. So the transformer will resist those high frequency signals more. Than it does the low frequency signals.

With some reasonable values, it is no different . AC power systems and not DC power systems . What makes the transformation is the difference in the number of turns on both sides, so it would be OK if you supplied 28VAC to get 280VAC. What happens if dc supply is given to the single phase transformer.
