It has high voltage stability, small ripple factor, excellent short circuit protection, and over-current protection.
5.It has high voltage stability, small ripple factor, excellent short circuit protection, and over-current protection.
II-VI Marlow recommends limiting the ripple factor to less than 10%, which will reduce the loss in performance to less than 1%.
Unfiltered full-rectified AC voltage has a ripple factor of approximately 48%, which can decrease the performance of the TEC by as much as 23%.
The excess current, at least a portion of which includes a ripple component induced by the ripple voltage, is shunted to ground.
A charge pump system and method that may provide large supply voltages and currents with reduced ripple voltage at reduced ripple frequency.
Current requirements are reasonably low, but ripple voltage is a major concern and must be minimized.
Distortion due at least in part to ripple voltage can be removed from a control signal that controls input current to the converter.
A ripple current reduction circuit includes a supply node (10) coupled to the output of a high ripple voltage source such as a charge pump (14).
The ripple amplitude and ripple frequency may be compared with corresponding references.
A ripple amplitude and a ripple frequency associated with operation of the active circuit may be monitored on the power supply line.
A memory (5) contains data defining a set point (SP) for the ripple frequency and ripple amplitude.
A controller (3) controls the current generator such as to set the ripple frequency (fR) and ripple amplitude (M).
The ripple amplitude and ripple frequency may be associated with an estimated power demand level of the active circuit on the power supply line based on the comparison.
Each corrugation has a first corrugation segment, a second corrugation segment disposed offset from and extending parallel to the first corrugation segment and an intermediate corrugation segment.
curvature ripple deformation and blisters
The apparatus comprises a rotatable corrugating wheel.
A ripple reference setting unit (320) sets a reference value (Irp#) of the ripple current width.
A curling device (3) has a roller for feeding the strip member (100) with reinforcing material and a curl guide.
The first and second corrugation segments extend vertically.
The system may store undulation values for a geographic area in an undulation grid model (146) or in a digital map.
This can avoid the generation of torque ripple.
The soleplate(1) is in wavilness shape.
A hair-treatment composition which contains a fermented rice bran/soybean extract, has excellent effects of protecting the hair, waving the hair and retaining the waved hair style, and relieves an offensive smell originating in perming agents.
The invention concerns a fin defining a general corrugated direction (D1), comprising a plurality of corrugations (123) alternately linked by a corrugation top (121) and a corrugation base (122).
At the interface of the two corrugated layers, the lines of corrugation in the first corrugated layer are substantially perpendicular to the lines of corrugation in the second corrugated layer.
Therefore, an air layer is formed between the insulator and the corrugation crest of the outer conductor, and a straight line section is provided in the corrugation crest of the outer conductor.
The speed at which they do this is called the frequency.
The exchangeable rollers (3, 4) have different wave shapes.
