Switching Frequency

electronics Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other Electric charge, electrically charged particles. It is a subfield ...

, switching frequency refers to the rate at which an

electronic switch In electronics, an electronic switch is a switch controlled by an Passivity (engineering), active electronic component or device. Without using moving parts, they are called solid state switches, which distinguishes them from mechanical switches. ...

Boost converter A boost converter or step-up converter is a DC-to-DC converter that increases voltage, while decreasing current, from its input ( ''supply'') to its output ( ''load''). It is a class of switched-mode power supply (SMPS) containing at least tw ...

Buck–boost converter The buck–boost converter is a type of DC-to-DC converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude. It is equivalent to a flyback converter using a single inductor instead of a tr ...
