Problems solved by technology

[0005]Although the above-mentioned AC-DC input conversion device uses simpler electronic components compared with the traditional UPS to relatively increase the power density, the semiconductor switching components used are still too large. Therefore, there are many isolation control drive circuits required. How to further simplify the controllable switching electronic components used is still a direction that the industry needs to work on.

Abstract

The invention discloses an input translator with multiple power sources and an uninterruptible power supply system with the input translator. In the input translator, each input power source is provided with an energy-storage inductance and an alternating-current switch circuit and subsequently connected with two energy-storage capacitors; when alternating current power supply is input, the flow direction of input current can be controlled by the control on the connection or disconnection of the alternating-current switch circuit so as to fulfill the functions of full-wave rectification and high power factor correction; when direct current power supply is input, the transfer mode from direct current to direct current power supply is realized also by the control on the connection or disconnection of the alternating-current switch circuit. Therefore, independently based on the condition of corresponding input power supply, each alternating-current switch circuit realizes the function oftransfer from alternating current to direct current and from direct current to direct current while maintaining the normal power supply to the energy-storage capacitor.

Description

technical field [0001] The present invention relates to an uninterruptible power supply system for a multi-power input converter device and the multi-power input converter device, especially to a multi-power input conversion device composed of an AC switch to achieve high power density, and has The utility model relates to an uninterruptible power supply system of the multi-power input conversion device. Background technique [0002] Figure 10 It is a structural block diagram of a traditional uninterruptible power supply system (UPS), which consists of an AC-to-DC and power factor correction device 102, a DC-to-DC device 104, a battery 105, a DC-to-AC device 106 and an output filter device 107 Constituted; when the mains 101 is normally supplied, the control switch 103 is in the cut-off state, and the DC-to-DC device 104 does not work, so the UPS starts in the online mode (Line Mode), which is converted from the AC to DC and power factor correction The device 102 converts ...
