The power supply unit is the part of the hardware that is used to convert the power provided from the outlet into usable power to many parts inside an electrical device. When the mains power fails, D3 reverse biases and D4 forward biases and battery takes the load. The input transformer is used to convert the incoming line voltage down to the required level of the power supply. Contact Us. Based on the electrical device’s electric specifications it may use AC power or DC power. Electrical Components used in Electronics and…, Cogeneration (CHP) Definition - Types of…, Maximum Power Transfer Theorem - Examples and Applications, What is Power Factor - Importance, Methods Used to…, Derive the Torque and Power Equation of a DC Motor. A capacitor is used to filter the AC ripples and gives to the voltage regulator. The switching losses in modern switches (like: MOSFETs) are much less compared to the loss in the linear element. Output voltage can be adjusted through the Pot VR1 to the desired voltage from 1.2 volts to 28 volts.D1 protects against C4 and D2 protect against C3 when switched off. It also has a battery back up to continue the work if power fails. The main features of this power supply include the following. While some require a regulated power supply, there are many applications where the output voltage needs to be varied. An SMPS designed for AC input can usually be run from a DC supply, because the DC would pass through the rectifier unchanged, Designing of Sequential Circuits Using PLA, Characteristics and Working of Avalanche Transistor Circuit, What is Band Stop Filter : Theory & Its Applications, What is Thermoelectric Generator : Working & Its Uses, What is a VU Meter : Circuit & Its Working, What is VRLA Battery : Construction & Its Working, What is Magnetic Hysteresis : B-H Curve & Its Applications, What is Synchroscope : Circuit Diagram & Its Working, What is Tan Delta Test : Its Principle and Modes, What is Graded Index Fiber : Working and Its Applications, Numerical Aperture of Optical Fiber & Its Derivation, What is Digital Frequency Meter and Its Working, What is Network Simulation : Types and Its Advantages, Graphical Processing Unit – Computational Functions & Its Architecture, Arduino Uno Projects for Beginners and Engineering Students, Image Processing Projects for Engineering Students, Design and Implementation of GSM Based Industrial Automation, Different Types of Voltage Regulators with Working Principle, MTech Projects for Electronics and Electrical Engineering, Half Adder and Full Adder with Truth Table, MOSFET Basics, Working Principle and Applications, How Does a PID Controller Work?
For example it can be put in a sleep mode, standby mode or switched off just by the use of computer software. There are some topologies normally used to actualize SMPS. Although they are more complex in design, ATX power supplies is more efficient and can be controlled by the use of various computer software. For instance, the microcontroller based circuits are generally the 5V DC regulated power supply (RPS) circuits, which can be designed with the help of different method for changing the power from 230V AC to 5V DC. These power supplies typically exhibit a lot of ripple voltage (i.e. A step-down transformer converts the 230V AC into12v.
