ac buck converter, ac buck converter Suppliers and Manufacturers

AC buck converters， also known as AC-DC buck converters， are widely used in various industries to convert AC power to a lower voltage. These converters are highly efficient and reliable， making them an essential component in many electrical devices. In this article， we will explore the working principle of an AC buck converter， along with some of the top suppliers and manufacturers in the market.

The working principle of an AC buck converter is quite straightforward. It operates on the basis of pulse-width modulation (PWM)， which involves controlling the duty cycle of a high-frequency switch to regulate the output voltage. The input AC voltage is first rectified to a DC voltage and then fed to an inductor. The inductor stores the energy during the on-time of the switch and releases it during the off-time. As a result， the output voltage is lower than the input voltage.

AC buck converters have numerous advantages over traditional linear regulators， including higher efficiency， smaller size， and lower heat generation. These converters are widely used in applications where the input voltage needs to be stepped down， such as power supplies for electronic devices， LED drivers， battery chargers， and motor control systems.

When it comes to sourcing AC buck converters， it is crucial to choose reliable suppliers and manufacturers. Here are some top players in the market:
