This document provides standard requirements and general guidelines for the design, performance, testing and application of low-voltage dry-type alternating current (AC) power capacitors rated 1,000V or lower, and for connection to low-voltage distribution systems operating at a nominal frequency of 50Hz or 60Hz.
Do low drop-out voltage regulators require a bulky off-chip capacitor?
Abstract: Demand for system-on-chip solutions has increased the interest in low drop-out (LDO) voltage regulators which do not require a bulky off-chip capacitor to achieve stability, also called capacitor-less LDO (CL-LDO) regulators.
Why is capacitor characteristic important in voltage regulator design?
life, and unpredictable circuit behavior . Thus capacitor characteristic is the key factor to the voltage regulator design. For long term strategic, it is important to support LDO with over 400nF/mm2 capacitanc nsities, operation voltage of above 10 volts, 60 - 100 micron
Which capacitor has the most negligible capacitance?
Assuming the same voltage ripple percentage, C 1 has the most negligible capacitance among the three capacitors in the proposed structure. Therefore, increasing the capacitance of this capacitor, which results in a voltage ripple of less than 5%, can significantly reduce the inrush current.
Why does a capacitor have a low inrush current?
On some levels, the inrush current is suppressed due to the presence of inductors. In other levels where the inductor is not in the capacitor charging path, the ripple voltage of the capacitor is low due to the proper charging sequence, resulting in limited inrush current.
What is the difference between 13 level and 17 level capacitors?
In the 17-level structure of 9, the inrush current has been reduced using inductance in series with the source. However, this structure has 14 switches and two diodes and requires a high-voltage level capacitor.
