An uninterruptible power supply system (100) has a flywheel system/battery combination (106) as a source of back-up DC power. When power is restored after a power outage, a controller (302) of the uninterruptible power supply system (100) controls the rectifier (102) to keep its DC output voltage sufficiently low so that only the flywheel system (118) of the flywheel system/battery combination (106) is initially recharged. Once the flywheel system (118) is recharged, the controller (302) is configured to raise the voltage of the rectifier's DC output voltage to the nominal DC output voltage ofthe rectifier (102), both for recharging the battery pack (116) of the flywheel system/battery combination (106) and to provide DC power to an inverter (104) of the uninterruptible power supply system (100). 不间断电源系统(100)具有作为备用DC电力源的飞轮系统/电池组合(106)。在电力中断之后恢复电力时，不间断电源系统(100)的控制器(302)对整流器(102)进行控制以使其DC输出电压保持足够低，使得初始仅对飞轮系统/电池组合(106)的飞轮系统(118)进行再充电。旦飞轮系统(118)被再充电，控制器(302)被配置成使整流器的DC输出电压的电压升至整流器(102)的标称DC输出电压，用于对飞轮系统/电池组合(106)的
