Embodiment Construction

[0044] The composite energy-saving uninterruptible power system (Hybrid green uninterruptible power system) of the present invention uses a multi-winding transformer (Multi-winding transformer) to perform bi-directional conversion of internal DC power high and low voltages, so as to use power conversion induction to generate additional DC power, so that the mains power is normal or In the case of failure, additional DC power can be output to provide external devices.

[0045] Here, the basic concept of the present invention is explained first. Please refer to FIG. 2 , which is a schematic diagram of the appearance of the composite energy-saving uninterruptible power supply system 20 disclosed in the present invention. As shown in FIG. 2 , the composite energy-saving uninterruptible power system 20 has an input port 200 , a plurality of AC output ports 204 and a plurality of DC output ports 208 . The input port 200 is connected to the mains network to accept the input of AC ma...

Abstract

The invention relates to an uninterrupted power system, which discloses a compound energy saving uninterrupted power system, a relevant bidirectional converter module and a power conversion method; wherein, the compound energy saving uninterrupted power system comprises a lifting pressure module, a battery, the bidirectional converter module and an inverter module. The lifting pressure module is used for converting alternating commercial power to high voltage direct current; the bidirectional converter module is provided with a multi-winding transformer which is used for bidirectionally converting the high voltage direct current to low voltage direct current to charge the battery or used for releasing and boosting the power of the battery; at the same time, the power conversion is carried out, the multi-winding transformer induces and produces additional direct current; the converter module is used for converting the power released and boosted form the battery to the alternating current. Therefore, the compound energy saving uninterrupted power system can generate the additional direct current when the commercial power is normal and when the commercial power has a failure, so as to enhance the efficiency of converting the battery energy in the uninterrupted power system to the external device to the maximum extent, which realizes the optimization of the energy saving.

Description

technical field [0001] The present invention relates to an uninterruptible power system (Uninterruptible Power System, UPS), in particular to a composite energy-saving uninterruptible power system with both an AC output port and a DC output port, and a related bidirectional converter module and power conversion method. Background technique [0002] Uninterruptible Power System (UPS) is a protection device for important equipment such as computer equipment, monitoring equipment, fire fighting equipment, and medical equipment. When the mains power is interrupted, the uninterruptible power supply system can replace the mains power urgently, so as to avoid the shutdown or damage of the protected equipment and other loads due to the instantaneous power interruption. On the other hand, when the power supply fails, for example, the voltage is abnormal (including the voltage is too high, too low), or the power quality problem is enough to affect the normal operation of the equipment...
