lülitussagedust

Lülitussagedus refers to the rate at which a switching power supply or electronic switch changes its state from on to off, or off to on. It is typically measured in Hertz (Hz) or kilohertz (kHz). A higher switching frequency allows for smaller and more efficient power conversion components, such as inductors and capacitors. This is because smaller components can store and release energy effectively at higher frequencies. However, increasing the switching frequency also leads to increased switching losses, which are the energy dissipated as heat each time the switch changes state. Therefore, there is a trade-off between component size, efficiency, and switching losses. The choice of switching frequency depends on the specific application requirements, balancing factors like power density, efficiency targets, and cost. Common switching frequencies can range from tens of kilohertz for general-purpose power supplies to hundreds of kilohertz or even megahertz for specialized high-frequency applications. Understanding lülitussagedust is crucial for designing and optimizing electronic power conversion circuits.
