A power supply and a transformer serve different roles in electrical systems. A power supply provides a stable output voltage and current from a source, converting electrical energy from one form to another, for example from alternating current to direct current. It often includes additional components such as rectifiers, regulators and filters to ensure that the output is consistent and suitable for powering electronic devices.
A transformer, on the other hand, only changes the voltage level of an AC signal using electromagnetic induction, without converting between AC and DC or regulating the output.
The main change between a power supply and a transformer is their function and complexity. A transformer only adjusts voltage levels through electromagnetic induction and does not include components to regulate or convert power.
In contrast, a power supply typically involves more complex circuitry, including transformers, rectifiers, and regulators, to convert and stabilize power for various applications.
The function of a power supply is to convert electrical energy from a source, such as mains power, into a stable, usable form of energy for electronic devices. It adjusts voltage and current levels to meet the specific requirements of the devices it powers, ensuring they operate correctly and safely.
A transformer is mainly used to change the voltage level of an AC signal.
It is commonly used in power distribution systems to increase or decrease voltage levels to ensure efficient transmission and safe use in residential and commercial applications. Transformers are also used in various electronic devices to isolate different parts of a circuit and adjust voltage levels as needed.
The difference between a charger and a power supply lies in their specific functions. A charger is a type of power supply designed specifically to charge batteries by providing a controlled current and voltage appropriate to the battery chemistry and capacity.
It often includes features such as load curves and cut-off mechanisms to prevent overloading. In contrast, a power supply provides a stable electrical output to power electronic devices and may lack the specific charging features required for batteries.
