本简报提出了一种应用于数字峰值电流 (DPC) 控制的开关 DC-DC 转换器的非对称双边沿调制 (ADM) 方法。展示了 DPC 控制的降压转换器与 ADM 和传统对称双边沿调制 (SDM) 的稳态和瞬态性能比较，并通过实验结果进行了验证。对比研究表明，带有ADM的DPC的稳态和瞬态性能优于带有SDM的DPC。
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.
