What Is Dc Power Supply Definition

A power supply is an electronic circuit designed to provide various ac and dc voltages for equipment operation.

What is dc power supply definition. Parts of a power supply. There was a time when some places were supplied with direct current dc power and others used alternating current power when a power supply has the description ac dc this means that the equipment can operate on either alternating current or direct current. Regulated power supply theory. This allows the voltage to stay stable regardless of the amount of current consumed by the load provided the predefined limits are not exceeded.

If you have ever wondered how to tell if a power supply is ac or dc you must know the differences between ac and dc power supplies and be. As a result power supplies are sometimes referred to as electric power converters some power supplies are separate standalone pieces of equipment while. It produces a dc supply from the mains or line supply ac sine wave. How to know if a power supply is ac or dc.

Dc in this context means direct current direct current is an alternative to alternating current frequently shortened to ac. Ideally a dc power supply unit commonly called a psu deriving power from the ac mains line supply performs a number of tasks. If you must use a dc dc power supply for a delicate device however you will need the cleaner output of a regulated power supply. Like the battery powering your kid s remote control car the smooth steady electrical current of dc power always flows in the same direction between positive and negative terminals.

Dc power is widely used in low voltage applications such as charging batteries automotive applications aircraft applications and other low voltage low current applications. A power supply is an electrical device that supplies electric power to an electrical load the primary function of a power supply is to convert electric current from a source to the correct voltage current and frequency to power the load. A dc power supply is a device that supplies electric energy of fixed polarity either positive or negative. All solar panels nowadays produce dc power.

Proper operation of electronic equipment requires a number of source voltages. A regulated dc power supply is essentially an unregulated power supply with the addition of a voltage regulator. This form of power is most commonly produced by sources such as solar cells batteries and thermocouples. It changes in most cases reduces the level of supply to a value suitable for driving the load circuit.
