6 FAQs about [Is the compensation capacitor adjustable ]
How a capacitor compensation circuit is controlled?
Through the logic drive circuit, pulse width modulation circuit, zero point detection circuit and power factor detection circuit, the on-off of the self-turning off device in the switch circuit was controlled to control the charging and discharging voltage of the compensation capacitor, and then the capacitor compensation current was controlled.
What is a compact capacitive compensation scheme?
In this article, a compact capacitive compensation scheme using a minimal number of compensation capacitors is proposed to realize series/series–parallel (S/SP) compensation for adjustable CV output and series/parallel–series (S/PS) compensation for adjustable CC output, achieving reduced system weight, volume, and cost.
What if a probe capacitor is over compensated?
A properly compensated reading should be 0.3V / 0V. If compensated capacitance is smaller (over-compensated?), the voltage drop at transient should be higher than 0.3V (spikes) or below 0V (dips) before resistor dominates and stabilize the reading to 0.3 / 0V. @KMC No, if the probe capacitor is over-compensating then it will be a little bigger.
Do adjustable output LDOS need a phase compensation capacitor?
Toshibaʼs adjustable-output LDOs are designed to operate stably without connecting a phase compensation capacitor (CFB) in parallel with the external resistor (R1) as shown in Figure 6.1.1. However, a phase compensation capacitor (CFB) may be added to ensure the prevention of oscillation or improve load transient response.
How does a phase compensation capacitor work?
The phase compensation capacitor (CFB) causes the feedback factor (β) to become dependent on frequency. This reduces the phase shift, causing the loop gain (Aβ) phase not to become inverted and thus preventing oscillation.
Should a Cout capacitor have a large equivalent series resistance (RESR)?
Care should be taken, however, because an output capacitor (COUT) with a large equivalent series resistance (RESR) might degrade the load transient response and other AC characteristics of an LDO.
