In PFC Charging mode, if the voltage of line drop to zero from higher voltage position, what will happen? If the mains voltage drops from high to Zero in PFC mode, the working state is changed from PFC to Inverter mode. At this moment, it is equivalent to the short circuit of the inverter output. * Over-current Protection * Grid Voltage drop Monitoring in Software 21 Thank You TM · Robert Miller1968 · · 45170 · 5,500 · 1,000 · 99.5 · · CRM · FutureElectronics.cn CONFIDENTIAL AND PROPRIETARY FAE FAE FutureElectronics.cn CONFIDENTIAL AND PROPRIETARY 1 3 2 4 5 7 6 1. 2. 3. 4. 5. 6. 7.
