Embodiment 1

[0032] Example 1, see figure 1 , an intrinsically safe uninterruptible power supply topology, including an input unit and a discharge circuit on the primary side of the transformer, an output unit and a charging circuit on the secondary side of the transformer, and the output unit is output to the intrinsically safe power supply (intrinsically safe type) through the safety barrier circuit. Uninterruptible power supply); the input unit is connected to the AC power supply, and the input unit side is also connected with a power failure detection circuit for detecting whether the AC power supply is powered off; the charging circuit and the discharging circuit are both connected to the backup battery, and the backup battery is also connected to a voltage detection circuit circuit; according to the detection results of the power failure detection circuit and the voltage detection circuit, the input unit, the charging circuit and the discharging circuit respectively control the on-off...

[0044] Example 2, see Figure 7 , showing a schematic diagram of the specific steps for switching between normal mode and charging mode, including steps:

[0045] S1: The input unit is connected to the AC power supply, the first switch S1 is closed by default, and before the switch control circuit interferes, it enters the normal mode by default. As long as the input voltage of the AC power supply is within the supportable voltage range, the intrinsically safe power supply can start to work. At this time, the intrinsically safe power supply works as an AC / DC power supply, and the output unit outputs 18V and 12V DC voltage respectively;

[0049] S1: The input unit is connected to the AC power supply, the first switch S1 is closed by default, and before the switch control circuit interferes, it enters the normal mode by default. As long as the input voltage of the AC power supply is within the supportable voltage range, the intrinsically safe power supply can start to work. At this time, the intrinsically safe power supply works as an AC / DC power supply, and the output unit outputs 18V and 12V DC voltage respectively;

Abstract

The invention discloses an intrinsically safe uninterruptible power supply topology and an implementation method thereof. The technical problems of low efficiency, large loss and temperature rise of an existing intrinsically safe power supply are solved. The topology comprises an input unit and a discharging circuit which are located on the primary side of a transformer, and an output unit and a charging circuit which are located on the secondary side of the transformer, and the output unit outputs power to an intrinsically safe power supply through a safety barrier circuit; the input unit isconnected with an alternating current power supply, and the input unit side is also connected with a power failure detection circuit for detecting whether the alternating current power supply is powered down; the charging circuit and the discharging circuit are both connected with a backup battery, and the backup battery is further connected with a voltage detection circuit; and the input unit, the charging circuit and the discharging circuit respectively control the on-off of respective circuit loops through a switch control circuit. Different working modes can be switched to under differentpower supply states, so that energy transmission only needs to be converted once, and the purpose of efficient conversion of an isolated power supply is achieved.
