Abstract :
Digital peak current (DPC) control, digital peak voltage (DPV) control, and digital peak voltage/peak current (DPV/DPC) control of buck converter with leading-edge modulation are studied and compared in this paper. The AC small signal transfer functions of control-to-output, input-to-output and output impedance are derived and the corresponding comparison studies are performed. Transient simulation is also performed to verify the analysis results.
