HYBRID ALTERNATING CURRENT UNINTERRRUPTIBLE POWER SUPPLY
专利汇可以提供HYBRID ALTERNATING CURRENT UNINTERRRUPTIBLE POWER SUPPLY专利检索，专利查询，专利分析的服务。并且This invention is concerning a new concept of alternating current (AC) uninterruptible power supply (UPS) without an autonomy limit. The power supply comprises a diesel engine (1), an asynchronous motor (2), an AC generator (3), an inverter (or a direct current (DC) to alternating current (AC) -DC to AC- converter) (4), a small battery (5) and a free wheel clutch (6). The system is intended to provide power to an AC distribution network without any interruption. This purpose is achieved as follows: when the mains power is available it is driving the asynchronous motor which, in turn, drives the AC generator. The load network is isolated from the mains by the two electrical machines (2 and 3), and the remaining components of the system are idle; when mains fails the inverter (4) drives the asynchronous motor (2) using the battery (5) power and keeping the AC generator (3) running. Meanwhile the diesel engine (1) starts, engages the free wheel clutch (6) and drives the common axis of the two electrical machines (2 and 3), to take over the load. The inverter (4) is switched off; when mains returns the asynchronous motor (2) is driven again and the diesel engine (1) is stopped. The system also includes a set of switches (S1 and S2) that switch on and off the equipment input and output, and an overall control unit (7). This system is intended to provide power supply to the electrical distribution network in buildings and installations where any interruption of AC power is not allowed, such as data processing centers, hospitals, airports, continuous operation industrial processes and other public buildings.，下面是HYBRID ALTERNATING CURRENT UNINTERRRUPTIBLE POWER SUPPLY专利的具体信息内容。
