Abstract
A resonant current limiting device, for a resonant current passage having a loop shape including at least one capacitor and a wiring passage with at least one inductor or inductance component, includes: an electric storage element connected in series with the capacitor; a driving power source; and a voltage controller that charges and discharges an electric charge in the electric storage element, which is supplied from the driving power source, controls a terminal voltage of the electric storage element to be a predetermined instruction voltage, and restricts a resonant current component flowing through the wiring passage.
