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.
The recommended practice is to size the capacitor to around 80% of the reactive power demand at no load condition. Overcompensation of motors is often is not intentional and usually happens when motors are relocated to a new starter location or when swapping motors with different magnetizing characteristics.
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.
That means a capacitor is connected in the feedback loop to compensate the op-amp frequency response. The miller compensation circuit is shown below. In this technique, a capacitor is connected to the feedback with a resistor across the output.
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.
This article will shed some light on how adding capacitors gives the distribution system the necessary reactive power to return the power factor to the required level. Capacitors act as a source of reactive energy, which accordingly reduces the reactive power that the energy source must supply. The power factor of the system is therefore improved.
