6 FAQs about [Capacitor compensation location]

What is the purpose of a compensation capacitor?

Objective of compensation is to achieve stable operation when negative feedback is applied around the op amp. Miller - Use of a capacitor feeding back around a high-gain, inverting stage. Miller capacitor only Miller capacitor with an unity-gain buffer to block the forward path through the compensation capacitor. Can eliminate the RHP zero.

How does a compensation capacitor affect frequency?

It is observed that as the size of the compensation capacitor is increased, the low-frequency pole location ω1 decreases in frequency, and the high-frequency pole ω2 increases in frequency. The poles appear to “split” in frequency.

Why do op amps need a compensation capacitor?

In addition, a better understanding of the internals of the op amp is achieved. The minor-loop feedback path created by the compensation capacitor (or the compensation network) allows the frequency response of the op-amp transfer function to be easily shaped.

Where is a series capacitor located?

The location of the series capacitor depends on the economic and technical consideration of the line. The series capacitor may be located at the sending end, receiving end, or at the center of the line. Sometimes they are located at two or more points along the line.

What is a capacitor bank?

Capacitor banks consist of small units connected in series, parallel, or both to get the desired voltage and Var rating. When the fault or overload occurs the large current will flow across the series capacitor of the line. Thus, the excessive voltage drop occurs across the transmission line.

How a series capacitor works?

Control of Voltage – In series capacitor, there is an automatic change in Var (reactive power) with the change in load current. Thus the drops in voltage levels due to sudden load variations are corrected instantly. The location of the series capacitor depends on the economic and technical consideration of the line.
