　　A wave energy device developed by No. 38 Research Institute of CETC (CETC38) passed state acceptance criteria on July 10.

　　The institute has made important progress in key technologies, such as hydraulic conversion and control, as well as power inversion. Constant output can now be realized and power can be stored, even in a wave of less than 0.5 meters in height.

　　The institute has been testing the technology for three years. Smart integrated control and wide-range inverter technologies are used to improve the efficiency of power conversion. The results proved to be successful, as the device can float and absorb waves, thus storing and generating power.

　　The head of the project, Wang Zhen, introduced the highlights of the device: “The floater rides waves like a ship and can return to the shore if a major storm appears. Installed capacity of the device is 5 kilowatts, but more can be installed in the future. Standard electricity can be provided through a grid connection.”
