Shunt Capacitor vs. Serial Capacitor
The equivalent capacitance of a shunt capacitor is larger than the capacitance of any capacitor in the capacitor bank. The difference in capacity When the capacitors are connected in series, the capacity decreases (for the calculation of the total capacity after connecting in series, refer to the parallel method of resistors), and the withstand voltage increases.
Frequency compensation
The method most commonly used is called dominant-pole compensation, which is a form of lag compensation. It is an external compensation technique and is used for relatively low closed loop gain. A pole placed at an appropriate low frequency in the open-loop response reduces the gain of the amplifier to one (0 dB ) for a frequency at or just below the location of the next highest …
