Apparatus for controlling supply power to conductive carrier of catalyst converter

An apparatus comprising:

• a conductive porous carrier of a catalyst converter for cleaning an emission out of an internal combustion engine, the conductive porous carrier carrying a catalyst of the catalyst converter, the conductive porous carrier being energized for warming of the catalyst;
• and
• a power supply controller configured to:
• determine whether a preset time has elapsed since a start of the power supply to the conductive porous carrier;
• carry out low power control when it is determined that the preset time has not elapsed since the start of the power supply to the conductive porous carrier, the low power control controlling the power supply to the conductive porous carrier for energization of the conductive porous carrier such that a value of the power supply to the conductive porous carrier when it is determined that the preset time has not elapsed since the start of the power supply to the conductive porous carrier is lower than a value of the power supply when it is determined that the preset time has elapsed since the start of the power supply to the conductive porous carrier;
• and
• continue the low power control when a temperature of the conductive porous carrier is lower than a preset evaporating temperature after the preset time has been elapsed since the start of the power supply to the conductive porous carrier.
