Functions of a Power Supply Unit
With the rise of technology the function of power supply unit now is extended to include protective measures, managing temperature, increase power efficiency and providing reliable and stable delivery of power to the components of computer system. lets begin to know the functions of a power Supply Unit one after another.
- Voltage Regulation: each components of computer system require a specific range voltage for proper functioning , now its the role of PSU’s to ensure that the output voltage remains within a specified range for giving a stable power supply for proper functioning of computer components. voltage fluctuation can be a severe problem for the functioning of sensitive electronic components.
- Current Limiting: if for some reason excessive amount of current starts to flow it will overheat and damage the computer components just to safeguard the electronic components from potential damage current limiting is applied. the task of current limiting is to ensure the current flow remain within the safe range preventing equipment failure simultaneously decrease the maintenance cost and increase the life span of the equipment.
- Overvoltage and Overcurrent Protection: Overvoltage and overcurrent are another threat for electronic components they pose significant amount of risks for equipment. so Now advance PSU’s are loaded with with a protection circuit to safe guard against overvoltage and overcurrent. presence of this protection circuit enhance the reliability of PSU’s by minimizing the chance of damage.
- Cooling Mechanisms: the process of conversion of the power generates heat and this heat if collected over a period of time produce over heating and overheating reduce the life span of computer components so to over come this challenge PSU’s are composed of fans or some other cooling option to dissipate the heat which is generated while the process of conversion of the power.
- Power Factor Correction (PFC): the efficiency by which by which electric power is converted into useful output is measured with help of power factor. the feature of power factor correction (PFC)is designed just to improve the power factor. addition of PFC to PSU’s increase the efficiency of power usage which helps the PSU’s in effective usage of power and simultaneously reduce the waste of energy.
What is Power Supply Unit (PSU)?
A PSU is a type of internal hardware used in information technology systems. Power Supply Units (PSUs), despite their name, transform power rather than providing it to systems. In particular, a power supply regulates the DC output voltage to the precise tolerances needed for contemporary computing components in addition to converting the alternating high voltage current (AC) into direct current (DC).
