Abstract

The application provides an uninterruptible power operation device, which includes an energy storage element, a charging circuit, a DC / DC conversion circuit, a first DC / AC conversion circuit, a drive circuit and a switching element, and the DC / DC conversion circuit is electrically connected to the energy storage element , converting the first DC power provided by the energy storage element into the second DC power, the first DC / AC conversion circuit is electrically connected to the DC / DC conversion circuit, the driving circuit is connected between the AC power supply and the load, and the switching element is connected to Between the DC / DC conversion circuit and the driving circuit, when the AC power supply is normally supplied, the switching element is in the cut-off state, and the driving circuit receives the first AC power from the AC power supply, and when the AC power supply is interrupted or abnormal, the switching element is in the conducting state, The driving circuit receives the second DC power of the DC / DC conversion circuit via the switching element.

Description

technical field [0001] This application relates to an uninterruptible power operation device, in particular to a drive circuit that can drive a load to quickly receive the electric energy provided by the energy storage element when the AC power supply is abnormal or interrupted, and the electric energy conversion efficiency is high and the cost is low Uninterruptible power operation device. Background technique [0002] Most precision electronic instruments and equipment need to rely on high-quality and stable power supply to maintain normal operation. The uninterruptible power operation device can not only ensure the reliability of the power supply source, but also provide high-quality power waveforms, so that the uninterruptible power operation device has become an optimal solution to ensure the reliability of power supply and provide high-quality power. For example, when the uninterruptible power supply When the operating device is applied to the elevator, the elevator c...
