Abstract
Electrical resistor heating with an electrical resistor heating circuitry which includes an AC power source of at least one phase, a plurality of heating resistors provided in a spatial arrangement, and switches to connect the AC power source with the heating resistors generating ON and OFF power states. Power scheduling is provided to adjust the power fed from the AC power source to the heating resistors at a desired partial-power level by ON/OFF switching a number of switches, wherein the power scheduling causes at least some of the switches to switch between the ON and OFF states in a staggered manner so that energization of the partial-power level of different resistors takes place, at least partially, non-simultaneously.
