System for optimal energy harvesting and storage from an electromechanical transducer

A device for collection of energy from mechanical disturbances and distribution of that energy to an electrical load. A transducer converts mechanical energy in the form of forces and displacements into electrical energy in the form of charge pulses. The charge pulses are rectified into a Direct Current (DC) power signal and accumulated and stored in an input storage element. A controlled conversion circuit assures that the voltage on the storage element is maintained within a predetermined optimal range for energy harvesting from the transducer, avoiding the application of peak voltages. The controlled conversion circuit can be hard wired and/or controllably adjustable to match a given disturbance characteristic. Only when the voltage is within the optimal range for a given type of disturbance will the controlled conversion circuit enable a DC/DC converter to further convert the stored energy to a voltage that is coupled to an output storage element. This technique optimizes power conversion by controlling the high voltage to low version conversion process by, for example, sensing the disturbance with external sensor or internal voltage of the system, and then using this information about the disturbance to control how and when the electrical conversion process will occur.

Integrated magnetics for a DC-DC converter with flexible output inductor

An integrated magnetic assembly that allows the primary and secondary windings of a transformer and a separate inductor winding to be integrated on a unitary magnetic structure is disclosed. The unitary magnetic structure includes first, second, and third legs that are physically connected and magnetically coupled. The primary and secondary windings of the transformer can be formed on the third leg of the unitary magnetic structure. Alternatively, the primary and secondary windings can be split between the first and second legs. Thus, the primary winding includes first and second primary windings disposed on the first and second legs and the secondary winding includes first and second secondary windings disposed on the first and second legs. The inductor winding may also be formed either on the third leg or it may split into first and second inductor windings and disposed on the first and second legs. In addition, one or more legs may include an energy storage component such as an air gap. This integration of the primary and secondary windings and the inductor winding on the unitary magnetic structure advantageously decouples the inductor function from the transformer function and allows the more optimal design of both the inductor and the transformer. The unitary magnetic structure may be coupled to a full bridge, a half bridge, or a push pull voltage input source to form a DC—DC converter.
