Abstract
An improved electric cooking appliance with a plurality of heating units arranged in two groups, a first group adapted for energization by a first AC power signal and a second group adapted for energization by a second AC power signal, 180.degree. out of phase relative to the first power signal. The heating units of the first and second groups are each connected to a common neutral power line. The output power of each of the heating units is controlled in accordance with the user selected power setting for each unit by selectively applying current pulses to each heating unit at a pulse repetition rate corresponding to the user selected power setting for that heating unit, with the application of current pulses to each heating unit being further controlled to minimize the concurrent application of current pulses to those heating units energized by the same one of the first and second power signals and to maximize the concurrent application of current pulses to those heating units energized by different ones of the first and second power signals, thereby minimizing the peak current pulses in the common neutral line.
