LVRT: Low Voltage Ride Through Circuit IGBT modules proposal for LVRT G IG PWM Converter PWM Inverter Clover circuit LVRT circuit Conventional system had be used the clover circuit. 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, 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. Fuji Electric Co., Ltd. All rights reserved. 0
