Claim Text:
1. A method for controlling an inductive load to reduce energy consumption by the inductive load, the method comprising: carrying out a first phase of operation, which comprises providing a primary electrical circuit having, in series, a DC power source, an inductive load, and a DC capacitor, and driving the inductive load by the DC power source, and charging the DC capacitor; carrying out a second phase of operation, which comprises providing a secondary electrical circuit that is partly concurrent with the primary electrical circuit, and driving the inductive load by discharging the DC capacitor while the DC source is temporarily disconnected and not part of the secondary circuit; and repeating the first phase of operation and the second phase of operation a desired number of times; wherein the inductive load is selected from the group consisting of motors, transformers, and equipment for lighting and heating.
