Japanese Patent JP3880069

B2

A customer side power management system includes a power transducer coupled to the electric lines from the utility. The power transducer senses stochastic peak power demands from the electric utility, and provides an output signal proportional thereto. The output signal is time averaged and provided to a comparator circuit. A predetermined threshold signal is also provided to the comparator circuit, and the two signals are compared. An AC-to-DC converter or power supply is coupled to the utility's electric line and provides a DC voltage on its output. The amplitude of the DC voltage is controlled by the output signal from the comparator circuit. A power isolation and distribution circuit and a storage battery are also included. The power isolation and distribution circuit is connected between the AC-to-DC converter and the storage battery. The power management system senses peak power demands for electricity, and switches a particular load of the customer from being powered by the AC-to-DC converter to the storage battery. When there is no peak power demand, the AC-to-DC converter powers the particular load.
