Smps Circuit China Tv Power Supply Diagram
The most commonly used type of power supply circuit is the smps switching mode power supply you can easily find this type of circuits in your 12v adapter or mobile laptop charger.
Smps circuit china tv power supply diagram. To get rid of this drawback in traditional dc power supply method engineers electronic designers are go with smps circuit. Power switch based smps for color television receivers a switched mode power supply smps typically consists of a power transformer secondary side rectifier diodes a switching semiconductor device a control ic and peripheral circuits. Low standby power while being always on highly efficient power management power monitoring for system protection. In this project we will build a similar ac to dc power supply circuit with 10w power rating.
Hence it is used for low power applications. If we need dc power supply for circuits we choose stepdown transformer based rectifier circuit it may give constant dc voltage under regulator ics but when the current fluctuations occurs at input power source then the dc output supply will also gets affected. If you understand the working of one power supply you will understand the most power supply circuit. In this tutorial we will learn how to build a 12v smps circuit that would convert ac mains power to 12v dc with a maximum current rating of 1 25a.
In this video i will explain tv power supply in details. The switch mode power supply circuit with very low output power of less than 100w watts is commonly a type of fly back converter smps it is very simple low cost circuit compared to other smps circuits. Simple circuit diagram of switched mode power supply the major feature of smps is the elimination of physically massive power transformers and other power line magnetic. The net result is smaller lighter package and reduced manufacturing cost reducing primarily from the elimination of the 50 hz components.
In this tutorial we will learn how to build a 12v smps circuit that would convert ac mains power to 12v dc with a maximum current rating of 1 25a. Power supply unit psu is a vital part in any electronic product design. Besides its basic function of supplying power to the load on the secondary side an smps may have to. Our integrated circuits and reference designs help you create a power supply for tv with lowest standby power and highest efficiency.
