Device, Method and System for Improving Electrical Power factor and Harmonic Power Quality Through Active Control of Power Quality Improving Electrical Appliances

This patent teaches “power quality-improving appliances” (hereafter referred to as “PQI appliances™”), which are appliances that will counteract the aggregate power factor and harmonic pollution currents within a building to greatly reduce a building’s relative aggregate reactive power and harmonic pollution currents. The PQI appliances simultaneously serve their primary functions as water heaters, space heaters, thermoelectric heating or cooling, range top and oven cooking, for examples. The PQI appliance is therefore a novel application for mundane existing appliance types to improve distribution power system quality.
