WebIn multiphase buck converters, phases are dynamically added or dropped based on the output load, to improve efficiency. This is typically achieved by programming a lookup table containing the range of threshold currents for each phase, independent of input voltage and switching frequency. In this work, an algorithm is proposed to recalibrate the threshold … WebThe median duration of virus shedding was 11.5, 28 and 31 days for presymptomatic, asymptomatic and mildly symptomatic patients, separately. Seven patients (38.9%) continued to shed virus after hospital discharge. During the convalescent phase, detectable antibodies to SARS-CoV-2 and RNA were simultaneously observed in five patients (27.8%).
