Switching Power Supply

Sunday, November 22, 2009

Switching power supply is a power supply form factor that incorporates high-frequency input switching to generate desired DC voltage. The use of switching regulator in the circuit makes it a regulated power supply system.

Switching Power Supply: An Introduction

Switching power supply provides modulated power supply by combining low-loss electronic components such as:

Inductors

Capacitors

Transformers

These power supply systems enable electronic connection through switches to regulate the power relay function. Effective circuit status switching between power on (saturation) and power off (cut off) generates required power supply for the device. The switching power method utilizes higher frequency than the AC supply, thus creating a continuous waveform. This facilitates the output supply to a smaller transformer than the input one.

Switching Power Supply: Advantages

The switching power supply method has gained global recognition as it offers the following advantages:

It can generate any voltage with little impact of input variations

It produces higher efficiency due to the use of low-loss components and duty cycles in power regulation

It has a small size due to high operating frequency

It features low heat generation

It is light weight

It produces minimal noise when switching frequencies of the power unit

Low-cost switching power units can produce noise due to input operations. Also, electronic design to connect inductors, capacitors and transformers pose severe challenges.

Switching Power Supply: Classifications

Switching power supply method can be used for four different input-output combinations:

AC to AC – in the form of a frequency changer

AC to DC – offline DC output

DC to AC – in the form of power inverter

DC to DC – in the form of voltage converter

A good switching power supply mode maximizes the performance of the electronic device in which it is installed. It demonstrates top performance by regulating input and output supply. Several electronic production companies manufacture switching power supplies and assist clients in choosing the best one for their devices. Custom switching power supply systems are also made for specific power regulation requirements.
