For series connected SCR’s dynamic equalising circuit consists of___________?

Correct answer: B. R and C in series but with diode across R

  • A. R and C in series but with diode across C
  • B. R and C in series but with diode across R
  • C. Series R and diode with C across R
  • D. Series R and diode with C across R

Explanation

A dynamic equalising network uses a series R-C circuit across each SCR, with a diode across the resistor. The capacitor controls transient voltage sharing, while the diode provides a rapid discharge path when required.
