A power converting apparatus that may increase a generation efficiency by receiving a power from a power source, producing electricity by rotating an output shaft connected to a generator using a portion of the received power, accumulating a remaining portion of the received power in an energy storage device, and rotating the output shaft using the accumulated energy when a power is not transmitted from the power source, the power source that floats in the ocean, performs irregular motions in vertical and horizontal directions by waves within a predetermined range, and generates an intermittent linear power, is provided.

An apparatus for driving links is provided and includes a base onto which an actuator is installed and a plurality of connection links connected to the base via a plurality of hinge pins, and the respective end of which is connected via the hinge pin to form a series of a driving lines. A plurality of capstans are disposed on the plurality of hinge pins, respectively and a wire allows the respective capstan to be rotated when the actuator drives by sequentially connecting the actuator and the respective capstans. A plurality of clutches are disposed on the plurality of hinge pins, respectively, and allow the connection links and the capstans to be rotated together, or allow the capstans to be rotated by connecting or disconnecting the ends of the connection links and the capstans, respectively.
