As an active approach to improve the stability degraded by the source subsystem interaction, the positive feedforward (PFF) control is proposed for the peak-current-mode-controlled buck converter. PFF control stabilizes the input port in the frequency range where the source subsystem interaction ...

Buck-boost converterPeak current modeDynamical effectWhen an output load of switching DC-DC converter exhibits the fingerprints of frequency dependent pinched hysteresis loops, the load can be regarded as a memristive load. By substituting a resistive load with the voltage-controlled memristive load ...
The power stage in an emulated peak current mode buck converter consists of the DC gain, APS, a low frequency pole, fP, the ESR zero, fZ, and a higher frequency pole, fL, set by the ratio of the sensed current ramp to the emulated current ramp. The power stage transfer function (...
The purpose of this paper is the performance evaluation of the proposed peak current mode buck converter, which is designed for different dc loads in dc distribution systems. The control circuit design is conducted for 5V and 3V output dc-dc converters. The design method is evaluated in terms ...
