    • An uninterruptible power supply (UPS) system includes an AC output, an inverter coupled to the AC output and configured to provide power at the AC output, and a switch configured to selectively couple a generator (e.g., an engine-generator set) to the AC output. The system further includes a control circuit configured to variably modulate the switch to gradually increase control power flow from the generator to the AC output while causing the inverter to concurrently provide power to the AC output. The switch may be a static switch that includes at least one silicon controlled rectifier (SCR), and the control circuit may be configured to control a conduction interval of the at least one SCR to control power flow from the generator to the AC output.
    • 一种不间断电源(UPS)系统包括在交流输出到反相器耦合到所述AC输出,并且被配置在所述交流输出,以提供功率,以及一个开关,配置为选择性地联接的发电机(例如,在发动机 - 发电机组)的 AC输出。 该系统包括一个控制电路进一步被配置为可变地调节开关,以逐渐从发生器到所述AC输出增加控制功率流,同时使所述逆变器,以同时将功率提供给AC输出。 所述开关可以是静态开关并包括至少一个可控硅整流器(SCR),以及所述控制电路可以被配置成控制所述至少一个SCR的导通间隔以控制从所述发电机到所述AC输出功率流。
