Definitions for "Switching Frequency"
The frequency at which the pulse-width modulator switches the dc voltage in a switching power supply.
The rate at which the DC voltage is switched on and off during the pulse width modulation process in a switching power supply.
The rate the solid state switches ( IGBTs) are turned off and on in the production of a PWM signal. In modern converters this rate varies between 18kHz to 100kHz, with higher rates offering better dynamic performance at the expense of efficiency and cost.
the actual number of targets to which the sensor can respond in a given time period, usually expressed as Hertz (cycles per second). Target-the part or piece being detected.
