| 摘要 |
The present invention relates to a PWM synchronization device for a parallel operation inverter system and, more specifically to a PWM synchronization device for a parallel operation inverter system in which multiple inverters including control units and communications units are operated in parallel, wherein the control units of the multiple inverters are connected through a synchronization signal line, the communications units of the multiple inverters are connected through a communications line, the control unit of a master inverter among the multiple inverters transmits synchronization signals through the synchronization signal line to the control unit of multiple slave inverters, and determines reception of the synchronization signals returned through the control unit of the multiple slave inverters, thereby controlling the operation of the multiple slave inverters. |
