Abstract
The disclosure relates to an exhaust gas aftertreatment system for treating exhaust gas from an internal combustion engine. The exhaust gas aftertreatment system includes an exhaust gas catalyst that includes an exhaust gas catalysis portion and a heating element. The heating element is configured to heat the exhaust gas catalysis portion. The exhaust gas aftertreatment system also includes: a voltage source which supplies the heating element with electric power for heating the heating element, and a DC to DC converter which is configured to control the electric power supply from the voltage source to the heating element. The exhaust gas aftertreatment system also includes a control unit which is configured to control the DC to DC converter based on the required electric power to heat the exhaust gas catalysis portion.
