科士达UPS电源还发展了将上述两种结合起来的旋转静止结合式科士达UPS电源，即在静止式科士达UPS电源上配置柴油发电-直流充电电机，当科士达UPS电源用电池放电时，电机并不启动，只有当电池容量消耗到限定值时才开始运转，给蓄电池充电，容量一般不大，一般在10kVA以下。多用在要求容量不大而又不怕吵闹的地方，如农村、边防和一些偏远的山区。
科士达UPS电源的控制电路也发展很快，由开始的分立元件简单控制发展到的微处理器控制，由硬件控制发展成软件控制。
Corstal UPS power supply has also developed a rotary static combined Corstal UPS power supply which combines the above two. That is to say, the static Corstal UPS power supply is equipped with diesel power generation-DC charging motor. When the Corstal UPS power supply discharges with batteries, the motor does not start. only when the battery capacity is consumed to a limited value, it starts to run and charges the battery. Generally, the capacity is not large. Below 10 kVA. It is often used in places that require little capacity and are not afraid of noise, such as rural areas, border guards and some remote mountainous areas.
The control circuit of Kosta UPS power supply has also developed rapidly, from simple control of discrete components to microprocessor control, from hardware control to software control.
