Description

Technical Field

[0001] This utility model relates to the field of power supply technology, specifically to a dual-channel DC power supply with an energy storage module. Background Technology

[0002] In the field of modern power electronics, dual DC power supply systems are widely used in scenarios with extremely high requirements for power supply continuity, such as communication base stations, data centers, and medical equipment, due to their high reliability and stability. By configuring two DC power supplies, this system can continue to supply power to the DC load from the other power supply when one power supply fails or its output is abnormal. This effectively avoids equipment downtime caused by a single power supply failure, greatly improving the system's fault tolerance and operational stability.

[0003] Existing dual DC power supply systems typically employ automatic transfer switch modules (ATS) to switch power sources. When the first DC power supply is functioning normally, the ATS switches to power the DC load from that supply. When the first DC power supply output is low or malfunctions, the ATS detects voltage instability or loss and automatically switches to the second DC power supply. However, during the switching process, short-term power outages are unavoidable due to factors such as the response time of the detection circuit and the action delay of the switching devices. For loads highly sensitive to power continuity, such as precision medical instruments and core network equipment, even short-term power outages can lead to data loss, equipment damage, or system crashes, severely impacting normal equipment operation and system reliability, and failing to meet the higher requirements for power continuity and stability in practical applications.

[0020] The present invention will be further described in conjunction with the following embodiments.

[0021] Depend on Figure 1 As can be seen, the dual DC power supply with energy storage module described in this embodiment includes a first DC bus 11, a second DC bus 12, a first DC power supply 91, a second DC power supply 92, an automatic transfer switch module 2, an energy storage module, and a DC load 3.

[0022] The first DC power supply 91 and the second DC power supply 92 are respectively connected to the input terminals of the automatic transfer switch module 2; the output terminals of the automatic transfer switch module 2 are respectively connected to the first DC bus 11 and the second DC bus 12; the DC load 3 is respectively connected to the first DC bus 11 and the second DC bus 12.

[0023] The energy storage module includes a supercapacitor 4; the input terminal of the supercapacitor 4 is connected to the first DC bus 11 and the second DC bus 12 respectively; the output terminal of the supercapacitor 4 is connected to the first DC bus 11 and the second DC bus 12 respectively.

[0024] Specifically, in this embodiment, the dual DC power supply with energy storage module has an automatic switching module 2 that can switch the power supply between the first DC power supply 91 and the second DC power supply 92. The automatic switching module 2 can detect if the voltage of the first DC power supply 91 or the second DC power supply 92 is unstable or disappears, and thus can automatically switch to another DC power supply module for power supply. In addition, the charging and discharging port of the supercapacitor 4 is charged during normal power supply, and remains in a static state after being fully charged. Once it leaves the charging state, it automatically enters the discharging state.

[0025] When the first DC power supply 91 is supplying power normally, the first DC power supply 91 shall give priority to supplying power to the DC load 3, and the automatic switching module 2 shall switch to the first DC power supply 91 for power supply. When the output of the first DC power supply 91 is low or a fault occurs, the automatic switching module 2 shall detect that the voltage is unstable or disappears and automatically switch to the second DC power supply 92 for power supply. During the switching process, there will be a short power outage. In order to ensure uninterrupted power supply to the unit, after the first DC power supply 91 fails, the supercapacitor 4 can supply power to the DC load 3. After the second DC power supply 92 is running stably, the supercapacitor 4 stops supplying power.

[0026] This embodiment, by setting a first DC power supply 91, a second DC power supply 92, and an automatic switching module 2, can automatically switch to the second DC power supply 92 when the first DC power supply 91 fails. Furthermore, by setting a supercapacitor 4, it can prevent short-term power outages during the switching process.
