Abstract:
An apparatus supplies voltage for an electrical heating catalytic converter. The apparatus includes: a direct current (DC) converter having an input for an input voltage and an output for an output voltage; a buck converter, which is configured to step down the output voltage of the DC converter to a supply voltage, which is lower than the output voltage, for the electrical heating catalytic converter; and a first electrical assembly, which is configured to rectify and smooth the supply voltage.
