EXTRA-NEW SERVICE DISTRIBUTION PROCEDURES AND PREPARATION WITH ADAPTIVE REGULATION OF THE SCALE FREQUENCY AND SPITZEN POINT

摘要

A low-power controller for a discontinuous switched mode power converter. The controller has an inductor current sensing circuit to measure the inductor current flowing through an inductive charge storage element as well as an output voltage sensing circuit to monitor output voltage. The controller monitors both the converter output voltage and the inductor current and uses this information to modulate a peak inductor current trip point and controller switching frequency according to a control law curve in order to regulate converter output voltage. The controller prevents the switching frequency from falling below a predetermined minimum frequency. The control law curve is selectable to specify controller operation according to a desired combination of minimum switching frequency and maximum peak inductor current.
