Embodiment

[0022] The development of a redundantly designed high-reliability power supply board in this embodiment includes: a heat dissipation structure shell, an excitation surge suppression circuit, a common mode choke circuit, a rectifier bridge circuit, a DC-DC switching power supply module, and an output LC Filter circuit, safety bleeder resistor circuit.

[0023] The following is a detailed description with reference to the accompanying drawings. Please refer to figure 1 . The input end is connected to 220VAC mains power, and there is a fuse F1 in series on the live wire to prevent short circuit or excessive current from burning the board. A varistor R7 is connected in parallel between the live wire and the neutral wire. When the voltage at both ends exceeds the threshold, the resistance value of the varistor R7 is 0, and the excessive current is exported in time to avoid damage to the subsequent circuit.

[0024] Please refer to figure 2 , two X capacitors C1, C2 are connect...

Abstract

The invention relates to a circuit topology, and especially relates to a redundancy-designed high-reliability power supply circuit topology. The circuit topology comprises a heat dissipation structure shell, and an excitation surge suppression circuit, a common mode choke circuit, a rectifier bridge circuit, a DC-DC switching power supply module, an output LC filter circuit and a safety bleeder resistor circuit which are arranged in the heat dissipation structure shell and connected in sequence. The circuit design is simple, and the LC filter circuit at the output end can ensure that the power supply board card outputs more stable 24VDC to the load. And the safety bleeder resistor circuit is designed, so that residual current on devices such as a large capacitor and the like can be quickly discharged after the power supply board card is closed, and the safety of personnel is protected.

Description

technical field [0001] The invention relates to a circuit topology, in particular to a high-reliability power supply circuit topology with redundant design. Background technique [0002] Any electronic device is inseparable from the power supply, but due to the limitations of the on-site environment, many electrical devices do not directly use the public power grid, but convert them in other ways to obtain the required form of electrical energy. In recent years, a wide variety of electronic equipment has developed rapidly, and the demand for power supplies, especially 24V industrial standard DC power supplies, has increased. In order to solve this problem, transformer power supplies have become the first choice. [0003] At present, industrial transformer power supplies generally have problems of large size, complex internal circuit devices, difficult heat dissipation, short continuous working time, and difficulty in providing high-power loads. Therefore, a high-power, high...
