Abstract

An electric heating installation (1) has at least two electric heating resistances (2) whose heating power can be cascaded by a control device (3). The control device has a controller (4) corresponding to the number of heating resistances which are each assigned to one heating resistance. The control device supplies each controller separately with a clocked pulse-shaped current. The controllers are controlled with a pulse-controlled modulation of the control device. The current pulses to the respective controller are displaced towards each other in time. The current pulses at the respective controller overlap each other in displaced time fashion. The heating resistances are PTC elements.
