Term of the day : 'Switching Frequency'

The rate at which the dc voltage is switched in a converter or power supply (PSU). In power factor corrected PSUs, there will be two switching frequencies, the boost converter switching frequency and the forward converter switching frequency. Additionally, some power supplies may have additional converters with their own switching frequencies (for example buck regulators).
