A series compensator, connected in series to an AC transmission line, for compensating for an electric amount, such as a voltage, current, phase or impedance, of the AC transmission line, comprises a first capacitor and a second capacitor connected in series to each other and connected to the AC transmission line, and a compensation current generator connected in parallel to the first capacitor. This structure eliminates the need for a bypass transmission line to simplify the main transmission line structure, has an enhanced current controllability, reduces harmonics to be generated and realizes an economical way of ensuring a large compensation amount.
