Abstract
A system for energy harvesting comprises a first interface for receiving energy from at least one renewable energy source (ERS); a second interface coupled to at least one load circuit; a third interface coupled to an least one primary energy storage (PES); a DC-to-DC converter connected to one of a single inductor and a single capacitor; a switching circuitry connected to the first, second, and third interfaces and the DC-to-DC converter; a control unit connected to the DC-to-DC converter and the switching circuitry, the control unit controls the system to operate in an operation mode including any one of: provide energy from the ERS to the at least one load via the DC-to-DC converter, charge the least one PES from the at least one ERS via the DC-to-DC converter, and provide energy from the at least one PES to the at least one load circuit via the DC-to-DC converter.
