Abstract :
Digital peak voltage (DPV) control and digital peak current (DPC) control of buck converter with leading-edge modulation are studied 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 between DPV and DPC control buck converter with leading-edge modulation. Transient time-domain simulation is also performed to verify the analysis results.
