PHASE DIFFERENCE REMOVAL BYPASS APPARATUS IN UPS OF APF CONFIGURATION
摘要
PURPOSE: A phase difference removal bypass apparatus in an UPS of an APF configuration is provided to remove a phase difference and perform a bypass operation when by-passing the UPS. CONSTITUTION: An input line has an input line voltage(AC). A link inductor(5) is coupled with the input line. An input switch(2) is coupled with the link inductor(5). An input switch MC(3) or an SCR switch(6) is coupled with the input switch(2). An output switch(4) is coupled with the input switch MC(3) or SCR switch(6). An output line is connected to the input line voltage(AC) through a bypass MC(1). The output line has an output line voltage(LO). An IGBT stack(7) is coupled between the input switch MC(3) or SCR switch(6) and the output switch(4). A battery switch(8) is coupled with the IGBT stack(7). A battery(9) is coupled with the battery switch(8).
