Mell What is the power supply means?
: a device providing power to electronic equipment and sometimes designated A, B, or C according to its function of heating vacuum tube cathodes, causing a flow of electron current in plate circuits, or applying a direct voltage in grid circuits.
What does the power supply do?
Despite the name, Power Supply Units (PSU) do not supply systems with power – instead they convert it. Specifically, a power supply converts the alternating high voltage current (AC) into direct current (DC), and they also regulate the DC output voltage to the fine tolerances required for modern computing components.
What is power supply and how do it works?
A power supply takes the AC from the wall outlet, converts it to unregulated DC, and reduces the voltage using an input power transformer, typically stepping it down to the voltage required by the load. For safety reasons, the transformer also separates the output power supply from the mains input.
What is the meaning of power supply in a computer?
A system that converts AC current from the wall outlet into the DC currents required by electronic circuits. A computer power supply converts AC into multiple DC voltages. For example, 12 volts is commonly used for drives, while 3.3v and 5v are used by the chips and other motherboard components.
Is a battery a power supply?
A power supply is an electrical device that supplies electric power to an electrical load. The source power may come from the electric power grid, such as an electrical outlet, energy storage devices such as batteries or fuel cells, generators or alternators, solar power converters, or another power supply.
What is a power supply and what is its purpose?
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. As a result, power supplies are sometimes referred to as electric power converters.
What are the components of a power supply?
A power supply is an electronic circuit that converts an ac voltage to dc voltage. It is basically consisting of the following elements: transformer, rectifier, filter and regulator circuits. Power supply units (PSU) are used in computers, amateur radio transmitters and receivers, and all other electronic equipment that use dc voltage as an input.
What do you do with power supply?
Within other devices, a power supply is used to transform various types of power into a compatible format to be stored, like solar energy to electrical energy. Perhaps the most common use of this type of device is within computer systems.
What is the function of a power supply in a computer?
Function of computer power supply. The function of power unit is to convert the electrical power (AC) comes from wall socket to a suitable type and voltage (DC) so that each component of a computer works properly. Luck of proper supply of power will damage a computer system. The power supply receives 120 or 230V and converts into 3.3V, 5.5V and 12V.
