| description | The invention provides an uninterruptible power supply system based on forced reversing of a solid-state change-over switch. The uninterruptible power supply system comprises the solid-state change-over switch, a diesel generator, an automatic change-over switch, a rectification unit, an energy storage unit, an inversion unit, a filtering unit and a control system. The invention provides an uninterruptible power supply system and method based on forced reversing of a solid-state change-over switch. The system can accelerate forced reversing of the uninterruptible power supply system based on an automatic change-over switch in an economic mode when a power grid breaks down. Compared with the forced commutation of the thyristor realized by LC resonance, the forced commutation method has the advantages that the control complexity and cost of the whole system are reduced, the conditions of power grid fault, load and the like are considered, the key power quality problems of voltage sag, non-unity power factor and |
