1. A system for energy harvesting, comprising:

  • 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 interface, the second interface, the third interface, 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 at least one 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.
