Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a multi-channel direct current power supply device capable of remote real-time monitoring and control. Background technique [0002] With the rapid development of pulse generation technology and time-domain array antennas, great progress has been made in array ultra-wide-spectrum high-power microwave radiation technology. In the ultra-wide-spectrum high-power microwave radiation system composed of hundreds of radiation units, the DC power supply device faces the following problems: First, the use of a single high-power DC power supply to supply power to the pulse sources of all radiation units is likely to bring about electromagnetic compatibility problems. Affect the stability and reliability of the system; second, it is necessary to monitor the voltage and current of each pulse source to determine the working state of the pulse source; third, the DC power supply device ...

Problems solved by technology

In the ultra-wide-spectrum high-power microwave radiation system composed of hundreds of radiation units, the DC power supply device faces the following problems: First, the use of a single high-power DC power supply for the centralized power supply of the pulse sources of all radiation units is likely to cause electromagnetic compatibility problems. Second, it is necessary to judge the working state of the pulse source by monitoring the voltage and current of each pulse source; the third is that the DC power supply device works in a strong electromagnetic environment, and the whole system needs to be shielded. It is convenient for personnel to operate safely in the shielding body, and the power supply device must have the ability of long-distance anti-jamming communication

[0003] At present, the common power supply method is that a high-power power supply supplies power to multiple radiation units at the same time. At this time, it is not possible to accurately monitor each load, or to use multiple power supplies for "one-to-one" power supply, but the monitoring data needs to be integrated.
