Switching frequency

Switching frequency refers to how often a device, such as a power converter or an electronic circuit, turns its power on and off in a given time period, usually measured in hertz (Hz). This rapid switching is essential for efficiently managing electrical power, converting voltage levels, or regulating current flow. Higher switching frequencies can improve performance and reduce size, but may also lead to increased heat generation and electromagnetic interference. Understanding switching frequency helps in selecting the right devices for applications like power supplies and motor controls, ensuring they work efficiently and reliably.
