class rizer.electrical_model.circuit.direct_rc_load_circuit.DirectRCLoadCircuit(source: rizer.electrical_model.components.source_circuit.ResistiveSourceCircuit, C: float, window_span: float, R_para: float = 0.0, r_p_rtol: float = 0.001, u_c_0: float = 0.0)#

Generator (no cable) driving a capacitor in parallel with R_p.

R_g and R_para are both plain series resistors with nothing between them (no cable, so no propagation delay separates them) – they simply add into the single series resistance RC_Rp_Circuit needs as its own R_par.

Parameters:

  • source (ResistiveSourceCircuit) – Voltage source with a constant series resistance R_g.

  • C (float) – Capacitance in parallel with the plasma resistance [F].

  • window_span (float) – Length of each re-solved window [s], passed to DrivenCircuitAdapter.

  • R_para (float, optional) – Additional parasitic series resistance [Ohm], independent of R_g. Default 0.0.

  • r_p_rtol (float, optional) – Relative tolerance on R_p drift within a window before it is forced to re-solve, passed to DrivenCircuitAdapter. Default 1e-3.

  • u_c_0 (float, optional) – Initial voltage across the capacitor (and across the plasma) at t=0 [V]. Default 0 V.

Raises:

  • TypeError – If source is not a ResistiveSourceCircuit.

  • ValueError – If R_para is negative, or source.R_g + R_para is not strictly positive (it is a divisor in RC_Rp_Circuit’s own ODE).

compute_plasma_voltage(t: float, R_p: float) → float#

Plasma terminal voltage, drop-in for the same call TransmissionLineResistiveCircuit answers.

Parameters:

  • t (float) – Time, in seconds.

  • R_p (float) – Plasma resistance at time t, in Ohm.

Returns:

Plasma terminal voltage, in Volts.

Return type:

float

generator_voltage(t: float) → float#

Return the source’s own open-circuit voltage at t, before the R_g/R_para divider.
