Problems solved by technology

[0002] Today's UPS (uninterruptible power supply system) and EPS (uninterruptible power supply facilities for firefighting) are not designed to achieve truly uninterrupted power supply. The existing solutions for traditional UPS and EPS use relay switching, and the contact of the relay There is a certain distance between the point and the swing arm, and the jump time is generally between 30mS-1S. This solution cannot be applied to the energy supply guarantee on precision equipment. When B standby power supply or C standby power supply obtains continuous power supply, if there is a time delay during switching, the terminal equipment will restart and lose data, such as national defense equipment, communication base stations, military detection and communication equipment, etc. instrument, the consequences are unimaginable

Embodiment 1

[0027] An embodiment of the present invention provides a power supply for seamless switching of multiple power supply modules, such as figure 1 As shown, it includes: a main power supply module that outputs the first voltage value to the outside, a backup power supply module that outputs the second voltage value to the outside, a rechargeable battery pack that outputs the third voltage value to the outside, and a supply for converting different input signals into stable output signals The output conversion module for the load; the main power supply module and the backup power supply module provide input signals to the output conversion module through the first diode D5 and the second diode D6 respectively, and the rechargeable battery pack directly provides input signals to the output conversion module. The cathode of a diode D5, the cathode of the second diode D6, the anode of the rechargeable battery pack and the input terminal of the output conversion module are connected to...

Embodiment 2

[0039] In order to further improve the performance of the power supply for the seamless switching of multiple power supply modules, and exert a better effect. Embodiments of the present invention make corresponding improvements on the basis of Embodiment 1, such as figure 2 As shown, the embodiment of the present invention also includes: a power conversion module for respectively detecting the output of the main power supply module and the output of the standby power supply module, the output conversion module has a feedback terminal for adjusting the power output, and the power conversion module detects the output of the main power supply module When both the power supply module and the backup power supply module have no output, a feedback signal for reducing the power output of the output conversion module is sent to the feedback terminal of the output conversion module. It can be seen that the power conversion module can control the output conversion module to reduce the p...

Abstract

The invention discloses a power source capable of achieving seamless switching of multiple power supply modules. The power source capable of achieving seamless switching of the multiple power supply modules comprises a main power supply module, a standby power supply module, a charging battery pack and an output conversion module. The main power supply module and the standby power supply module offer input signals to the output conversion module through a first diode and a second diode respectively. The charging battery pack directly offers input signals to the output conversion module. A cathode of the first diode, a cathode of the second diode, an anode of the charging battery pack and the input end of the output conversion module are connected to the same node. According to the power source capable of achieving seamless switching of the multiple power supply modules, by the adoption of the power supply modules with different output voltages and with the combination of the switching function of the diodes, the power supply sequence is determined according to a high-low voltage rank, the power supply module with the low output voltage guarantees real continuous power output in an online standby mode, power supplied by the commercial power is preferably output and used, a mechanical switching switch of an existing UPS power source is eliminated, cost is low, the switching is conducted between the different power supply modules in sequence, and the switching time is nearly zero.
