BuckBoost

Description

The BuckBoost module describes a converter structure, where the boost- and buck-converter stages can be configured arbitrarily. For both converters, the voltage and efficiencies can be set accordingly. If the input/output voltage is not configured or set to zero, it is assumed that no converter is used (e.g., Vout = Vcap + Eout = 1 or Vin = Vcap+ Ein = 1).

This model also implements an overvoltage protection of the capacitor, i.e., the input efficiency is set to 0 if VCap > v_ov, and the quiescent current of the converter(s) can be configured.

Parameters

Parameter	man./opt.	Value	Description
v_out	o	Voltage in V	Output voltage of buck converter (if v_out > 0, else Vout = VCap) (Default: 0)
v_in	o	Voltage in V	Output voltage of boost converter (if v_in > 0, else Vin = VCap) (Default: 0)
efficiency_out	o	(0 ... 1)	Efficiency of buck converter (Default: 1)
efficiency_in	o	(0 ... 1)	Efficiency of boost converter (Default: 1)
v_ov	m	Voltage in V	Over-voltage threshold
i_quiescent	o	Current in A	Quiescent current of converter (Default: 0)
