    Switching Power Supplies

    Switching power supplies, also known as a switch mode power supply (SMPS), are electronic devices that provide efficient and regulated power conversion from one voltage level to another. They are widely used in a variety of electronic devices, including computers, smartphones, televisions, industrial equipment, and more.Switching power supplies offer several advantages over traditional linear power supplies, such as higher efficiency, smaller size, and lighter weight. Here at RS, we stock an extensive range of high-quality, high-efficiency SMPS from industry leading brands including Mean Well, XP Power, Carlo Gavazzi, TRACOPOWER, Cosel, Cotek and of course RS PRO.

    How does a Switching Power Supply Work?

    The basic principle behind switching power supplies involves rapidly switching an electronic switch (usually a transistor) on and off at a high frequency. This creates a square wave-like signal, which is then fed through an inductor and/or a transformer. By controlling the duty cycle (the ratio of on-time to off-time) of the switching signal, the output voltage can be regulated and transformed to the desired level.

    Where are Switching Power Supplies Used?

    Switch power supplies are used in a wide range of applications due to their efficiency, compact size, and versatility. Here are some common areas where SMPS are used: Consumer Electronics, telecommunications, industrial applications, power generators and distributors, automotive, medical equipment, aerospace and defence, renewable energy, home appliances, LED lighting, networking equipment, data centres and gaming and entertainment.

    Is the Switch Mode Power Supply AC or DC?

    A switching mode power supply is designed to convert one form of electrical energy into another. In most cases, the input to an SMPS is AC (alternating current), but the output is typically DC (direct current).The switch mode power supply performs the necessary conversions to ensure that the output voltage is stable, efficient, and suitable for powering electronic devices that typically require DC power.
