Abstract
Energy management method and apparatus for use in conjunction with a demand-limited alternating current circuit having a plurality of separate loads, including resistive loads, and means for automatically shedding certain of the loads when the actual demand of the circuit exceeds the demand limit. The actual demands of the loads in operation are sensed and the demands of at least certain of the operative resistive loads are separately sensed. The duty cycle of the power applied to at least certain of the operative resistive loads is reduced by switching these loads 'off' and 'on' synchronously with the zero points of the applied voltage. An overall reduction in the actual demand of the circuit is thereby effected when the failure to make such reduction would otherwise cause certain of the operating loads to be completely shed.
