How to perform SMPS with circute diagram?
A switched-mode power supply (switching-mode power supply, SMPS, or simply switcher) is an electronic power supply that incorporates a switching regulator in order to be highly efficient in the conversion of electrical power. Like other types of power supplies, an SMPS transfers power from a source like the electrical power grid to a load (e.g., a personal computer) while converting voltage and current characteristics. An SMPS is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage.Unlike a linear power supply, the pass transistor of a switching mode supply switches very quickly (typically between 50 kHz and 1 MHz) between full-on and full-off states, which minimizes wasted energy. Voltage regulation is provided by varying the ratio of on to off time. In contrast, a linear power supply must dissipate the excess voltage to regulate the output. This higher efficiency is the chief advantage of a switch-mode power supply.Switching regulators are used as replacements for the linear regulators when higher efficiency, smaller size or lighter weight are required. They are, however, more complicated, their switching currents can cause electrical noise problems if not carefully suppressed, and simple designs may have a poor power factor.
What is code switching in easy terms?
Code switching is the process of switching back in forth between two languages in the same conversation. It is sometimes done because some words are easier to say in one language or the other.
What is a Variable 0 - 12V dc power supply?
A variable power supply has a control to adjust the DC output voltage from 0 to 12 volts. It is used for testing electric project's such as amplifiers and other electric devices. It can be used to replace other fixed voltages power supplies such as the srandard 3 volt, 5 volt, 9 volt and 12 volt units.
Why cmos is used more than other transistor?
Lower power dissipation (except at very very high switching rates, as almost all the power dissipated by CMOS is during switching).
How science technology and society related to each other?
Technology supplies the tools that society uses, science supplies the understanding of how the technology works.
Types of AC-DC power supply?
Answer for countries in Europe and other world areas running a 50 Hz supply service.AC power supply is 230 v supply used in our homes for switching on fans, bulbs etc. where as DC power supply is used for switching on our laptops, charging our mobiles phones, i pods etc.
What does naval supplies mean?

Where is used smps?
A switched-mode power supply (switching-mode power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a source, like mains power, to a load, such as a personal computer, while converting voltage and current characteristics.An SMPS is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage. thus it is used in all electronic devices that are directly connected to a DC power source
