It can not be possible to supply to out put power for grid line, because DC bus voltage is zero voltage at clover circuit operating, Jan. 2015 It can be possible to supply to out put power for grid line, because DC bus voltage is kept at LVRT circuit operating. Therefore this system is more higher reliability system. MT5F27336 © Fuji Electric Co., Ltd.
