1. A power generation device based on the time-varying magductance principle, consists of an electric energy generation unit, a power conversion unit and an electric energy storage unit, wherein
the electric energy generation unit comprises a time-varying magductance component configured to form a closed conductor loop in a magnetic circuit with constant magnetic flux, and the time-varying magductance component generates an induced current by changing the magductance parameter of the time-varying magductance component; and
the power conversion unit comprises switching device and a circuit for electric energy transmission; and the electric energy generated by the time-varying magductance component is stored into the electric energy storage unit through controlling the switching device of the power conversion unit.
