Abstract
A controlled-power delivery system may operate with RF waves for supplying continuous and suitable power to a load. The controlled-power delivery system may include one or more receiving antennas, one or more rectifiers, a first boost converter, a charger, a storage element, and a second boost converter. The first boost converter may step up the rectified DC voltage obtained from the receiving antenna and rectifier to supply a suitable voltage level that can be used for charging the storage element. The second boost converter may increase the voltage from the storage element to a suitable level that may satisfy the power requirements of the load. The charger in conjunction with the first and second boost converters may be configured to allow a plurality of modes of operation for delivering power to the load and charging the storage element.
