A switched mode (or switching) power supply is one that uses pulse-width modulation technology, rather than linear technology, to provide the voltage required to a load. Often, it requires no power transformer, nor is a great deal of power developed across the power supply, which reduces size, cost, and heat. It works by the fact that inductors resist a change in current. There is a high voltage power supply, often 160VDC running directly off the AC line. A transistor or other switching device supplies power to an inductor, which is in series with the load. There is also a Schottky diode from the input side of the inductor to ground. When the transistor is on, voltage is supplied to the inductor, which supplies current to the load. When the transistor is off, back voltage from the inductor is shunted to ground through the diode, and the inductor continues to supply current to the load. A pulse-width modulator monitors the load voltage, and adjusts the transistor on time at a high frequency. The average current flow, and thus the average load voltage, remain constant. Since the transistor turns on hard - it is in saturation - very little voltage drop is across it. As a result, very little power is developed, resulting in less overall heat.
SMPS stands for switched mode power supply

not all but there rare many of them in this usage

Rectification is the process of converting alternating current into direct current. The smoothest power supply is a 'switched mode' supply.
It sounds like you have a power supply problem. The capacitors on the switched mode power supply have changed value or failed completely. Replace or repair the power supply section.
SMPS stands for Switched-Mode Power Supply. It is an electronic power supply that efficiently converts electrical power using switching devices such as transistors. SMPS are commonly used in electronic devices to provide stable and regulated power to sensitive components.
An SMPS is a switched-mode power supply. It is used to convert an unregulated power input into a regulated power output, often altering the voltage. In a modern computer, several components may be powered from the same power supply but will often require different regulated voltages. The SMPS fulfils this role.
The Main difference between a Switched Mode Power Supply and an Uninteruptable Power Supply is the function. SMPS are like a conditioner of electricity supply for a building, house, etc. UPS are the emergency backup power supply for vital computer based systems
There are quite a number of various ways that one can find out how to switch mode power supply. This depends on what device the mode of needs to be switched. The device's website would be the best way to find out. One could also contact the customer support services of the device's provider.
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.
