∙ 1 − 0.33 = 8V (2) where • DmaxΔIL is the duty cycle where the maximum inductor ripple current occurs Knowing VSUPPLY_maxΔIL, the desired ripple ratio, and the switching frequency, Equation 3 is used to calculate the inductance value at 1.6A load (VSUPPLY = 6V to 9V). ...
Due to component tolerances and power loss of the regulator, the peak current limit should be set some margin above the calculate peak inductor current. A margin of 20% to 40% (MI_LIMIT = 0.2) is a good starting point. Equation 5 is used to calculate the desired peak inductor current ...
To estimate a magnetic field gradient value, use the appropriate equation for magnet μ0Mr ≈ 1–1.2 T), a given distance (in meters), substitute and then calculate the field gradient. the magnet characteristic μ0 Mr (e.g. for a NdFeB the magnetic addition in Eq....

An interpolation figure was constructed to determine how luminosity and CCT affect visual experience and to calculate the equal color difference line to understand its relation. The following conclusions were reached: (1) The emitting principle causes CIE and CIEF light sources to exhibit a ...
As a term and word, "logistics" originates from the Greek word "logisitki" deriving from the verb "logizomai", which means to think deeply about something and to calculate the consequence of actions. Logistics can be dated back to the Roman Empire, ancient Greece and Byzantium, where ...
The 29 measures are used to calculate 12 criteria, which are aggregated into four principles, and these principles are then translated into an overall assessment. The number of cows (sample size) to be assessed was determined by the WQ protocol. On-farm assessment was carried out by a ...
