Abstract

The invention discloses a monitoring device applied to a high-power direct-current power-supply system. The monitoring device comprises a current-measuring unit, a voltage-measuring unit and a voltage-analyzing unit, wherein the current-measuring unit, the voltage-measuring unit and the voltage-analyzing unit are connected in parallel with a load at the output end of a high-power direct-current power supply. The current value, the voltage value, the voltage-ripple effective value, the noise-peak value and the noise spectrum output by direct current are detected and analyzed in real time, and the current value, the voltage value, the voltage-ripple effective value, the noise-peak value and the noise spectrum are displayed through a display unit, so that workers can monitor the operating state of the high-power direct-current power supply in real time, and the normal working and operation of the system are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electronics and power supply, in particular, it relates to a monitoring device applied to high-power DC power supply. Background technique [0002] With the development of power electronics technology and the wide application of a large number of electronic devices, the demand for large-capacity and high-reliability power supply systems is increasingly urgent. The technology of converting the mains three-phase AC power into a stable DC power supply through filtering and high-frequency transformation processing has been widely used in various related industries. [0003] The high-power DC power supply in the prior art has three-phase alternating current at its input, including power modules connected in parallel with each other. Interference signal, the filtered three-phase alternating current then enters the AC-DC rectifier to be converted into direct current, and the direct current enters the DC-AC rect...
