Abstract :
A capacitor current feedback pulse train (CCF-PT) control technique for switching DC-DC converters is proposed and applied to the control of a buck converter operating in continuous conduction mode (CCM). The analysis and experimental results show that the CCF-PT control technique can effectively eliminate the low-frequency oscillation phenomenon that exists in conventional pulse train (PT)-controlled CCM switching DC-DC converters.
