Bypass mode

This paper presents the design of high efficiency PWM/PFM Buck Converter with Bypass mode for battery-powered products. In this design, when the input voltage falls below 1.9V, the converter automatically enters Bypass mode. When input voltage rises upper 2.1V, the converter operates in PWM mode or PFM mode depending on load current.

Apogamy is a unique asexual reproduction in the ferns, in which somatic cells of gametophytes go through dedifferentiation and then differentiate into haploid sporophytes bypassing fertilization. Restricted to the lack of genomic information, molecular mechanisms of apogamy have remained unclear.

The fundamental frequency of the electric cabinet is sensitive because of many attached devices. To bypass this complex problem, the average spectral acceleration ðSaÞ in the range of period that cover the first mode period is chosen as an intensity measure on the fragility function. The nonlinear time history analyses for cabinet are conducted using a suite of 40 ground motions. The obtained curves with different approaches are compared, and the variability of risk assessment is evaluated for restrained and anchored models.
