Nonlinear Average Current Control Using Partial Current Measurement

APEC 07 - Twenty-Second Annual IEEE Applied Power Electronics Conference and Exposition, 2007
This paper presents a nonlinear average current control method which regulates the true average of the inductor current by using the switch current as the feedback signal. The method is simple and requires no compensator design. Unlike existing average current control where the control bandwidth is limited to about one tenth of the switching frequency,
