A string of thyristors is connected in series to withstand a dc voltage of Vs = 25 kV.The maximum leakage current and recovery charge differences of thyristors are 15mA and 175 µC, respectively. A derating factor of 12% is applied for the steady-stateand transient voltage sharings of thyristors. If the maximum steady-state voltagesharing is 1200 V, determine (a) the steady-state voltage-sharing resistance R for eachthyristor and (b) the transient voltage capacitance C1 for each thyristor.
