Digital predictive V2 control of switching DC-DC converter with trailing-edge, leading-edge and double-edge pulse modulation implementation are proposed and studied in this paper. The control laws for each modulation are proposed and compared. Transient characteristic analysis is performed on the digital predictive V2 control with trailing-edge modulation, the simulation results made by Matlab/Simulink show that it has good transient performance under load perturbation. Experimental system was set up to verify the analysis and simulation results by employing FPGA.
