具有稳定周期行为和改进轻载效率的DC-DC变换器电压模式数字脉冲跳跃控制

A pulse skipping modulation (PSM) technique improves the light load efficiency in a dc-dc converter by selectively skipping a few clock pulses. However, in existing PSM schemes, the number of charge and/or skipped cycles cannot be predefined. Therefore, it is difficult to predict the ripple parameters and ensure a stable periodic behavior. Further, it becomes difficult to further minimize power lo...
