Switching power supplies | Choosing the Right Power Supply
There are 2 types of power supply technology: Linear power supply Switching power supply Linear power supply This type of power supply provides one or more stabilized and constant DC voltages despite the fluctuations of the network.  This system consists of a transformer, a rectifier, a filter and a regulator. The transformer reduces the amplitude of the power grid voltage, the rectifier converts the AC voltage into a DC voltage, the...

How to choose this product
switching-power-supply

A switch-mode power supply, also known as a switching power supply or SMPS, is a non-linear type of electrical supply. It is much smaller and more compact than linear power supplies for a given output.

Applications

Switch-mode power supplies are used in device and machinery power-supply subsystems. Their compactness has led to decreased device size. However, they generate unwanted electrical noise, making them unsuitable for certain applications. They can be found in most electronic equipment (computers, monitors, measuring devices, etc.).

Technologies

Two main types of switch-mode power supplies exist. A direct conduction supply (forward) instantaneously transmits power; an inductive storage supply (flyback) stocks electrical energy in an energy storage inductance for later use. Electrical efficiency of 78% is quite common. A high-frequency switching unit allows the use of transformers in an energy-efficient mode. This increases conversion efficiency and thermal dissipation.

How to choose

Choosing a switch-mode power supply's technology involves determining desired power. Applications requiring little power usually utilize flyback-type supplies (LCD monitors, television, DVD player, etc.).

Advantages

- Compactness
- Excellent efficiency
- Low thermal dissipation

Disadvantages

- Electrical noise
- Presence of harmonics
- EMC filtering is necessary
