  • 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
