배터리 충/방전 시스템을 위한 10㎾ AC 회생장치 개발

In this paper, AC regenerative device for battery charge/discharge system at the discharge mode was proposed. A regenerative device is able to transfer surplus power to grid. AC regeneration function is able to improve the energy efficiency. At the parallel system driving, all systems construct same driving mode. AC regenerative device is able to be utilized at eco-friendly energy like photovoltaic, wind power and geothermal heat. The economic effects are expected by regenerative energy.
