Why DC transformer is not used?
DC transformers are not commonly used because the transformers rely on the principle of electromagnetic induction, which only works effectively with alternating current (AC). In a transformer, alternating current flowing through the primary winding generates a changing magnetic field, which induces a voltage in the secondary winding by electromagnetic induction. Since DC does not have alternating current, it cannot create the changing magnetic fields necessary for induction to occur effectively in a transformer.
Technically, DC can be used with a transformer, but it would require additional components such as a DC-AC inverter to convert the DC input to AC before it can be used by the transformer. This approach adds complexity and cost to the system, making it less practical compared to using AC directly with a transformer.
Can DC be used by a transformer?
DC is not used for long distance transmission of electrical power as it suffers from higher power losses and requires larger conductor sizes compared to AC. In AC transmission systems, voltage can be easily increased using transformers, allowing power to be transmitted over long distances at high voltages, reducing power losses and minimizing conductor size necessary. Additionally, AC allows the use of techniques such as phase shifting and reactive power compensation, which improves the efficiency and stability of the transmission system.
Why is DC not used for transmission?
Transformers cannot operate directly in a DC power system because DC does not support the changing magnetic fields necessary for electromagnetic induction in a transformer. Without alternating current, there is no periodic reversal of the magnetic field, which is essential for inducing voltage in the secondary winding of the transformer. As a result, the transformers are not suitable for use in DC systems without additional conversion equipment.
Using transformers on DC is not practical due to the fundamental differences in the behavior of DC versus AC. Since transformers rely on the principles of electromagnetic induction, which are intrinsically linked to alternating current, they are not well suited for use in DC systems. Instead, other technologies such as DC-DC converters or solid-state devices are used for voltage conversion and power distribution in DC systems.
We trust this overview of Why DC transformer is not used? has been clear.
