    • An emergency power system is connected between an AC voltage source (10) on the input and a load (Z) on the output. The emergency power system ensures a stable voltage on the output, even if the AC voltage received from the AC voltage source (10) is irregular or is interrupted briefly. The emergency power system comprises an AC/DC converter (14) coupled between its output terminals and an AC regulator (20) positioned between the input and the output. The AC/DC converter (14) is coupled to a chargeable battery (12) and serves as a charging rectifier for the battery (12) in normal operation and as an inverter in emergency operation, the battery voltage being converted to AC voltage on the output of the emergency power system. This can be done without changing the control of the converter (14) and the regulator (20). The AC regulator (20) is built as a controllable current generator supplying on its output an AC current which is in phase with the AC voltage received from the AC voltage source (10). Irrespective of the energy direction through it, the AC/DC converter (14) maintains the predetermined AC voltage (VOUT) across the output terminals of the emergency power system. The system moreover includes a comparison means (28) which senses and compares the battery state to a predetermined reference and supplies a signal in response to this. The intensity of the current supplied by the regulator (20) is controlled in response to the signal generated by the comparison means (28), so that in terms of energy the system is in power balance.
    • 应急电源系统连接在输入端的交流电压源(10)和输出端的负载(Z)之间。 即使从交流电压源(10)接收到的交流电压不规则或短暂中断,应急电源系统确保输出上的稳定电压。 应急电源系统包括耦合在其输出端子与位于输入端和输出端之间的AC调节器(20)之间的AC / DC转换器(14)。 AC / DC转换器(14)耦合到可充电电池(12)并且在正常操作中用作电池(12)的充电整流器,并且在紧急操作中用作逆变器,电池电压被转换为交流电压 输出应急电源系统。 这可以在不改变转换器(14)和调节器(20)的控制的情况下完成。 AC稳压器(20)被构建为可控电流发生器,在其输出端上提供与从AC电压源(10)接收的AC电压同相的AC电流。 不管通过它的能量方向如何,AC / DC转换器(14)在紧急电力系统的输出端子之间维持预定的交流电压(VOUT)。 该系统还包括比较装置(28),其将电池状态与预定参考值进行比较并提供响应于此的信号。 响应于比较装置(28)产生的信号来控制由调节器(20)提供的电流的强度,使得在能量方面,系统处于功率平衡。
