III. How to use capacitors? As a relatively common electronic component, capacitors have a wide range of uses. The following content gives you a brief introduction to the 9 most common scenarios where capacitors are used: Stopping DC, bypass (decoupling), coupling, filtering, temperature compensation, timing, tuning, rectifier, and energy

Capacitive compensation

Capacitive compensation refers to the addition of capacitors to an electrical system to counteract the effects of inductive loads, thereby improving the power factor. By introducing capacitive elements, the system can reduce the phase difference between voltage and current, leading to more efficient energy usage and decreased losses in power

Compensation capacitor in amplifier

Compensation capacitors can be added for filtering effects. The compensation capacitor may be used to reduce bandwidth, for example in a case where that signal frequency is not needed and the designer wishes to reduce noise. As Michael has pointed out, some feedback capacitors can contribute to stability problems. To learn more about this

Series Compensation

Frequency compensation

Feed-forward or Miller compensation uses a capacitor to bypass a stage in the amplifier at high frequencies, thereby eliminating the pole that stage creates. The purpose of these three methods is to allow greater open loop bandwidth while still maintaining amplifier closed loop stability.

Frequency compensation

Parameter ζ is set by a compensation capacitor: smaller ζ results in faster response, but more ringing and overshoot. Most amplifiers use negative feedback to trade gain for other desirable properties, such as decreased distortion, improved noise reduction or increased invariance to variation of parameters such as temperature.

How does a capacitor work?

This capacitor creates a pole that is set at a frequency low enough to reduce the gain to one (0 dB) at or just below the frequency where the pole next highest in frequency is located. The result is a phase margin of ≈ 45°, depending on the proximity of still higher poles.

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.
