摘要： A wind-power generation system with an over-speed protection is disclosed. The system is provided to convert wind energy into mechanical energy by a wind turbine, and mechanical energy is converted into electric energy by the wind turbine driving a generator. Also, electric energy is delivered to a power grid. The wind-power generation system mainly includes an AC crowbar, a fuse, and a DC chopper. The AC crowbar or the DC chopper is provided to consume superfluous energy outputted from the generator, thus providing an over-load operation to brake the wind turbine when the wind turbine operates under a first stage over-speed operation. Finally, the generator is isolated from the generator-side converter by disconnecting the fuse when the wind turbine operates under a second stage over-speed operation.

摘要： An uninterruptible power supply module is provided. The uninterruptible power supply module comprises an input terminal, a direct-current voltage source, a control module, a control arm-bridge module, an inductive element, a power source selection switch, and a switch element. The switch element is turned on before the power source selection switch is connected to the inductive element so that the direct-current voltage supplied by the direct-current voltage source is modulated by the control arm-bridge module to generate an output alternating current voltage to the load. And the switch element is turned off, i.e. not conducting electricity, after the power source selection switch is connected to the inductive element and the direct-current voltage source. Thereby, the use life of the power source selection switch element and the reliability of the uninterruptible power supply module are both increased.
