Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This is a model of a DC-DC inverter. The level of detail of the DC-DC inverter may be chosen from ideal averaging or switching.

Reference voltage is limited to actual battery voltage.

Battery voltage and motor current are measured.
