What is SMPS?
A switched-mode power supply 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 DC or AC source to DC loads, such as a personal computer, while converting voltage and current characteristics. Unlike most electronic power supplies, the switching regulator of a SMPS operates in a solid-state mode, meaning it operates with very low magnetic field-independently of the power supply. A solid-state switching regulator eliminates the noise created by noise in transistors or capacitors, which can be caused by temperature variations, external magnetic fields, the environment and loads.
How does it work?
The SMPS converts the DC generated by the DC/DC converter to a voltage and current suitable to power a load with the supply’s circuitry and switching regulator. This is done by changing the bias voltage of the load’s variable resistor. The output bias voltage is then applied to a larger-than-normal capacitor, which in turn converts it to an AC signal. The signal then is distributed to the output pins of the power supply, where it can be rectified and connected to loads such as an electronic component, hard drive, printer, or another load. Another effect of the SMPS is that it also acts as a fixed-voltage rectifier, as explained below. When an AC waveform enters the power supply, the capacitor’s voltage drops.
Why is it better than other power supplies?
The inclusion of a power regulator within the SMPS eliminates the need for a transformer, resulting in a more compact and powerful power supply. These switches can also be smarter by more intelligently regulating power, which will prevent power spikes and sudden surges which may cause equipment failure. SMPSs are also more reliable due to the built-in protections and standards that include overvoltage, overcurrent, short circuit, and over temperature protection. For many home and business owners, a power supply is required in order to provide enough power to their computers, printers, televisions, radios, fans, and other electronic devices. For those people looking for a reliable, high-quality and efficient home power supply, they have some options to consider.
When should I use SMPS?
Some power supply manufacturers market SMPSs as much more powerful than their DC counterparts and therefore should be used whenever possible. However, the tradeoff is that SMPSs require a bigger power supply, and you may require additional electrical infrastructure to support the DC load, which can affect the use of SMPSs. For example, if a computer uses a desktop computer with a 2.5-kilowatt power supply, that desktop may require two power lines, one of which may need to be used to power the AC-to-DC converter in the power supply. In the end, you should consult with your IT engineer to determine if you need an SMPS. If you need one, contact the power supply vendor to make an inquiry. Some vendors offer individual models of SMPSs.
SMPS switches control the flow of DC power between the input and output of a power supply and can be used to control the power supply in the case of protection circuits. SMPS switches can be used to control high-power electronic devices such as solid-state relays, sine wave oscillators, and motors. Since they are very efficient and have many advantages, it is advisable to invest in an SMPS power supply.
