Abstract

The invention discloses a medium-small power switching non-impact UPS device. The medium-small power switching non-impact UPS device comprises a rectification module, a storage battery, a first boost module, a second boost module, an inversion module, a change-over switch and main controller. The rectification module is used for rectifying and processing a voltage output by the mains supply and converting a single-phase mains supply to a direct current. The storage battery is used for providing power when the mains supply fails or the electric energy quality of the mains supply is out of a range required by UPS. The first boost module is used for boosting a voltage output by the storage battery. The second boost module is used for boosting a voltage output by the rectification module and a voltage output by the first boost module up to 300V. The inversion module is used for inverting the second boost module into 220V alternating current and outputting the current. The change-over switch is used for switching the mains supply and the storage battery. The main controller is used for detecting an output voltage of the inversion module and an output voltage of the second boost module, and performing switching on-off control on the inversion module and the second boost module. The UPS device is high in sensitivity, high in precision, good in anti-interference performance, safe, reliable, long in service life and convenient to popularize and use.
