Switching Frequency
Electronics Engineering · Electrical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: The rate at which a switching regulator's power transistor turns on and off per second, typically measured in kilohertz or megahertz. It influences the size of external components, efficiency, and output ripple characteristics.
Example in context
“Selecting a higher switching frequency of 2 MHz allowed the use of a smaller inductor, reducing the overall power supply footprint.”
“2 MHz'lik daha yüksek bir anahtarlama frekansı seçmek, daha küçük bir indüktör kullanılmasına izin vererek genel güç kaynağı ayak izini azalttı.”
Where engineers use it
Switching frequency is a key parameter chosen early in power supply design. It affects inductor and capacitor sizes, switching losses, electromagnetic interference, and transient response. Engineers often select it based on efficiency and board space trade-offs.
Synonyms: fsw, switching rate, oscillator frequency
Antonyms: line frequency
In Electrical Engineering
The rate at which a power electronic switch (e.g., MOSFET or IGBT) turns on and off per second, measured in hertz.
“The IGBT inverter switches at a frequency of 10 kHz to reduce audible noise and minimize filter size.”
Practice: can you use “Switching Frequency” at work?
You are designing a compact DC-DC converter for a portable device. The initial design uses 500 kHz but the inductor is too large. Discuss the implications of raising the switching frequency to 2 MHz.
Show a model answer
“Increase the switching frequency to reduce the size of the magnetic components.”
