Types of Power Supply Units
Power supply units can be primarily categorized into two different categories based on different approaches to power regulation
1. Linear Power Supply
Operation: functioning of linear power supply is very basic it function by regulating the output voltage by dissipating excess power in form of heat as it is clearly seen energy is not efficiently used so this method is less efficient compared to alternative methods. now in sort in these power supplies simply adjust the voltage by absorbing the extra power and making the process less efficient.
Applications: Applications of linear power supply comes into role when simplicity is prioritized over optimal power efficiency . when uncomplicated functionalities are more significance mostly in low-power scenarios deployment of linear power supply is common. these powers supply unites are preferred when its required a reliable and uncomplicated power delivery but they are not applicable if its required to maximize the energy efficiency.
Example:
Audio Amplifier: Linear power supply is used in audio amplifier because straightforward voltage regulation mechanism ensure the constant and reliable voltage .
Patient Monitoring System: Linear power supply is used in patient monitoring system because their require the accurate and continuous monitoring of vital signs which just require constant and reliable voltage which is provided by linear power supply.
2. Switching Power Supply
Operation: Switching power supply operates by regulating the output voltage with help of a dynamin mechanism using a high frequency switching circuit. the approach is innovative it increase the efficiency by minimizing the loss of energy and simultaneously reduce weightage of the power supply unit.
Applications: Switching power supply are deployed in present days computer and other electronic devices extensively their compact design and their ability to reduce energy wastage enhance their efficiency and make them extra-ordinarily fit for the applications where space optimization and energy efficiency plays a vital role.
Example:
Laptop/mobile Power Adapters: switching power supply are used in Laptop/mobile power adaptor as they are compact in size and also efficient to use this two factor make them best for the portable devices such as mobile and laptop.
LED Lighting: switching power supply are used in LED lighting as they reduce energy wastage and for LED’s its important to reduce power consumption for the efficient lighting.
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).
