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).
Learn MoreThe first power electronic devices for reactive power compensation were static var compensators (SVC) combining thyristor-controlled reactors (TCR) and thyristor-switched capacitors (TSC) that appeared in the 1970s [6]. As the power switches with forced turn-off capability, such as IGBT or GTO, became commercially available, …
