pvpltools.power_conversion.adr_converter_core(v_norm, p_norm, b)

Calculate power loss in a power converter for the given normalized operating conditions and the ADR model “b” coefficients.

The ADR model input and output quantities are normalized using a nominal voltage and power level, allowing the converter characteristics to be scaled up or down easily.

Voltage and current values may correspond to electrical inputs or outputs, and may be DC or AC, hence different types of converters can be modeled. However in general a set of coefficients is only valid for a specific type.

Parameters:

• v_norm (numeric) – Normalized voltage and power, unitless. These arguments must be “broadcastable” to the same shape.

• p_norm (numeric) – Normalized voltage and power, unitless. These arguments must be “broadcastable” to the same shape.

• b (1-D or 2-D) – Nine model “b” coefficients as described in [1].

Returns:

p_loss_norm – Normalized power loss, unitless.

Return type:

numeric
