具有自适应电压定位机制的自适应导通时间控制Buck变换器的开关频率稳定技术

Unpredictable continuous conduction mode switching frequency variation that occurs commonly in ripple-based control can lead to serious electronic-magnetic interface noise problems and thus increase the effort required for designing noise filters. Sensorless load current correction and dynamic tolerance window techniques are proposed in this paper to reduce the frequency variations caused by condu...
