Abstract
An electric power system comprises a plurality of capacitors connected in series, a plurality of DC-AC conversion circuits converting each DC voltage of the plurality of capacitor to an AC signal that an AC component equivalent to the inter-terminal DC voltage of each of the capacitors is superimposed on the respective DC voltages and a plurality of condenser couplers break the respective DC voltages and output the AC components respectively, and a processing circuit detecting the inter-terminal DC voltage of the corresponding capacitor from the AC component.
