[0032] The invention provides a hybrid uninterruptible power supply system, which makes full use of the advantages of static UPS and rotating UPS, provides timely and reliable uninterrupted power supply for downstream load equipment, and ensures the safe operation of downstream load equipment.
[0033] In order to make full use of the advantages of the static UPS and the rotating UPS, the present invention combines the static UPS and the rotating UPS to form a hybrid UPS. It has the advantages of static and rotating UPS at the same time, such as small output impedance, small output power distortion, high reliability, strong transient overload capability and fast dynamic frequency response. There are three common types of hybrid UPS, one is offline hybrid UPS, which is composed of offline UPS and rotary UPS, the other is online interactive hybrid UPS, which is composed of online interactive UPS and rotary UPS, and the third is On-line hybrid UPS is composed of on-line UPS and rota...
