Abstract
An asymmetrical dual-edge modulation (ADM) method applied to digital peak current (DPC)-controlled switching dc-dc converters is proposed in this brief. Steady-state and transient performance comparison of DPC-controlled buck converters with ADM and conventional symmetrical dual-edge modulation (SDM) is presented and verified by experimental results. Comparison studies show that the steady-state and transient performances of DPC with ADM are better than those of DPC with SDM.
