Switching power supply at large industrial plants or in home use are installed for many reasons. These devices are designed to provide electrical energy to various equipment, thereby creating optimal conditions for the correct and uninterrupted operation of all connected systems. At the moment, the market for such products offers a wide selection of laboratory power supplies, voltage stabilizers, AC / DC converters and probes for various purposes and configuration. There is a clear division of devices into converting (inverters, network adapters) and storing energy reserves (batteries and accumulators, charging units, as well as generators and UPS).


Modern Switching power supply are built primarily using a pulse voltage conversion circuit, devices on which are distinguished by low weight and reliability. Despite the different production technologies and the introduction of innovative solutions, the essence of their work is to obtain tens of kilohertz pulses from the pre-rectified mains voltage, which then go through the filtering and rectification stages. There is also a good alternative – linear sources with a diode rectifier. They are easy to repair, and at the moment they are gradually decommissioning, like network adapters with a transformer inside. Depending on the devices that need to be supplied with reduced direct current, power supply devices are subject to classification. At the same time, a number of distinguishing features are taken into account, the main of which is the scope:

    • General purpose;
  • Industrial;
  • Blocks for desktop computers and laptops.

Thanks to the wide selection, it is possible to choose mobile and stationary equipment, which is selected in accordance with personal requirements and specifics of use. Stationary ones are mainly intended for testing new circuits, for commissioning and tuning, and they are decided to buy them mainly for professional purposes, therefore the price is much more expensive than for general-purpose products. At the same time, they differ in serious additional functions that none of the other categories have.
