In either case, some form of phase compensation scheme will be required to stabilize the circuit. No Evil Is Without Its Compensation: Feedback Capacitor Calculations. It is common knowledge that adding a bypass capacitor in parallel with the feedback resistance provides the requisite compensation to guarantee sufficient phase margin (Figure 6).
Shunt compensation is used in power transmission systems to control the voltage at their point of interconnection (POI) [19]. Shunt compensation is classified into different types according to their technology. The main types of shunt compensations are: (a) Shunt capacitors, which are used to increase the voltage by injecting reactive power at ...
