WebV 2 control can be interpreted as an implementation of current mode control with direct voltage feedback and load current feedback. The load current feedback dramatically reduces the output impedance. The model is extended to enhanced V 2 control. WebAnother well-known technique today, which has also been around since the 80s, senses the peak current in the power switch or inductor, and turns the switch OFF at a programmed level of current. This technique is called current-mode control (“CMC”). Keep in mind it was not “brand-new” at the time.
