Transient Recovery Voltage (TRV) Reduction Resistor Function.

Function to find the resistor value that will reduce the TRV by a specified percentage.

Parameters:

  • C (float) – Capacitance Value in Farads.

  • L (float) – Inductance in Henries.

  • reduction (float) – The percentage that the TRV should be reduced by.

  • Rd0 (float, optional) – Damping Resistor Evaluation Starting Point, default=500

  • wd0 (float, optional) – Omega-d evaluation starting point, default=260*k

  • tpk0 (float, optional) – Time of peak voltage evaluation starting point, default=10*u

Returns:

  • Rd (float) – Damping resistor value, in ohms.

  • wd (float) – Omega-d

  • tpk (float) – Time of peak voltage.
