In electronics, switching frequency refers to the rate at which an electronic switch performs its function. Switching frequency is an important design and operating parameter in systems such as:
The Class-D amplifier, an audio power amplifier with a switched-mode output. Various types of electric power conversion equipment: Boost converter Buck–boost converter Buck converter Chopper Switched-mode power supply Power inverter Motor controls, such as Variable-frequency drives
This frequency is also used in different types of DC-DC converters like Battery Discharge Regulator, Universal Bus Regulator, Auxiliary Bus Regulator etc., switching frequency refers the switch on or off the circuit in the particular frequency
