1. A system comprising:
a first module, wherein the first module comprises a power receiving module configured to receive an input power from an energy source;
a second module, wherein the second module comprises a power conversion module configured to convert the input power to an output power;
a third module, wherein the third module comprises a control module for configuring the first module and the second module to perform a charging operation and a discharging operation;
wherein the first module, the second module and the third module are functionally integrated to perform multiple modes of the charging operation and the discharging operation;
wherein the third module controls an impedance during the charging operation and the discharging operation by tuning an impedance matching network by controlling switching of capacitors and inductors of the impedance matching network; and
wherein the multiple modes of the charging operation and the discharging operation comprises at least one of:
charging of an electric charge storage through a power grid;
charging of the electric charge storage through a wireless source;
discharging of the electric charge storage to a DC voltage load; and
discharging of the electric charge storage to an AC voltage load.
