class fastga_he.models.propulsion.components.connectors.inverter.components.perf_casing_temperature.PerformancesCasingTemperature(**kwargs)[source]

Bases: ExplicitComponent

Computation the temperature of one of the inverter casing based on the losses on the previous point. The temperature can be calculated for one module and generalized to the two other since we assume they are identical. Assumes that the thermal constant is so small that we can consider that the losses equals the power we can dissipate in steady state.

According to Semikron technical information, the heat transfer from junction to heat sink can be either modeled with a casing plate considered common to all junctions (consequently, a common R_th_cs for all modules), or consider individual R_th_cs. We will choose the former.

Can be seen in [Err19] and [TLS+22].

Store some bound methods so we can detect runtime overrides.

initialize()[source]

Perform any one-time initialization run at instantiation.

setup()[source]

Declare inputs and outputs.

compute(inputs, outputs, discrete_inputs=None, discrete_outputs=None)[source]

Compute outputs given inputs. The model is assumed to be in an unscaled state.

An inherited component may choose to either override this function or to define a compute_primal function.

Parameters:

  • inputs (Vector) – Unscaled, dimensional input variables read via inputs[key].

  • outputs (Vector) – Unscaled, dimensional output variables read via outputs[key].

  • discrete_inputs (dict-like or None) – If not None, dict-like object containing discrete input values.

  • discrete_outputs (dict-like or None) – If not None, dict-like object containing discrete output values.

compute_partials(inputs, partials, discrete_inputs=None)[source]

Compute sub-jacobian parts. The model is assumed to be in an unscaled state.

Parameters:

  • inputs (Vector) – Unscaled, dimensional input variables read via inputs[key].

  • partials (Jacobian) – Sub-jac components written to partials[output_name, input_name]..

  • discrete_inputs (dict or None) – If not None, dict containing discrete input values.
